**Aditya Mittal on Topological Representations of Circle**This video shows several different ways of representing a circle and what it is to be homeomorphic to a circle. It tries to help build a very conceptual understanding of the topological concept without all the formalism and equations. I make no claim to having made any of these concepts. I am only reiterating in an easy to understand and concise manner.**Homeomorphism, LMMS dubstep**Just started using LMMS - some others of mine:**AlgTop2c: Homeomorphism and the group structure on a circle (cont.)**This is the third video of the second lecture in this beginner's course on Algebraic Topology. We give the basic definition of homeomorphism between two topological spaces, and explain why the line and circle are not homeomorphic. Then we introduce the group structure on a circle, or in fact a general conic, in a novel way. This gives a gentle intro to the definition of a group. It also uses Pascal's theorem in an interesting way, so we give some background on projective geometry.**Explicit construction of block mesh duals by addition of local dual contributions**Xevi Roca and Josep Sarrate Laboratori de Càlcul Numèric (LaCàN), Departament de Matemàtica Aplicada III, Universitat Politècnica de Catalunya web: www-lacan.upc.edu Several algorithms have been devised in order to generate hexahedral meshes for any geometry. During last decade alternative methods based on the dual of a hexahedral mesh have been developed [1]. This work is devoted to obtaining a valid topological block decomposition of a given domain without a previous discretization of the boundary [2]. To this end, we propose an approach to directly construct a valid dual of the block mesh. The proposed algorithm is composed by two main steps 1- we create a reference mesh, a tetrahedral mesh, of the domain to decompose into blocks; and 2- we create the dual of the block mesh by using the new concept of local dual contributions. These contributions are planar surfaces inside the tetrahedra of the reference mesh. The union of these contributions define a discretized version of the dual surface arrangement. To test the possibilities of the local dual contributions we propose a new block meshing algorithm based on this concept. The tool automatically adds local dual contributions following a set of hierarchical rules. These rules ensure that the local dual contributions define a valid discretized representation of the dual of the final block mesh. Specifically, adjacent local dual contributions define regions that are locally homeomorphic to: (i) one dual surface (a layer ...**AlgTop2a: Homeomorphism and the group structure on a circle**This is the first video of the second lecture in this beginner's course on Algebraic Topology. We give the basic definition of homeomorphism between two topological spaces, and explain why the line and circle are not homeomorphic. Then we introduce the group structure on a circle, or in fact a general conic, in a novel way. This gives a gentle intro to the definition of a group.

We give the basic definition of homeomorphism between two topological spaces, and explain why the line and circle are not homeomorphic. Then we introduce the group structure on a circle, or in fact a general conic, in a novel way. This gives a gentle intro to the definition of a group. It also uses Pascal's theorem in an interesting way, so we give some background on projective geometry.**Rational Plane Curves**Given a curve C={f=0} of degree d in complex projective 2-space, one may ask, if C admits a parametization, ie if there is a rational map from projective 1-space to C with dense image. C minus the singularities of C is a 1-dimensional complex manifold, ie a real surface. As a topological space it is homeomorphic to a compact oriented surface minus finitely many points. Compact oriented surfaces are topologically classified by their genus g, the number of handles one has to attach to a sphere to obtain the given surface. Necessary and sufficient for a curve to admit a parametrization is the condition g=0. If rp is the multiplicity of C at p and C has rp different tangents at p, then g is (d-1)*(d-2)/2 minus the sum of rp*(rp-1)/2 for all points p of C. If the equation f has rational coefficients, a parametization with rational coefficients can be given, up to a field extension of degree 2, which may be necessary if d is even. In the example shown the curve C (drawn in red) is given by a polynomial of degree 5 and has 3 double points and one triple point, so the formula above reads g = 4*3/2-1-1-1-3 = 0, hence C admits a parametrization. The theorem of Bezout implies, that the curve C of degree 5 intersects a quadric in 5*2 = 10 points, counted with multiplicities. Hence the system of all quadrics (shown in green) through the singular points of C has 5*2-3-2-2-2 = 1 moving point of intersection with C. Elimination gives the coordinates of this point in terms of the ...**Good Will Hunting Maths Problem**The problem Matt Damon's character solved in 'Good Will Hunting' - Homeomorphically Irreducible Trees of degree ten.

The full lecture is available (in 24 parts) here on YouTube, or it can be downloaded (like all of our lectures) in its complete form from the Gresham College website, in video, audio or text formats: Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website.**PFW 2 - Topology Class**pfw**AlgTop14: The Ham Sandwich theorem and the continuum**In this video we give the Borsuk Ulam theorem: a continuous map from the sphere to the plane takes equal values for some pair of antipodal points. This is then used to prove the Ham Sandwich theorem (you can slice a sandwich with three parts (bread, ham, bread) with a straight planar cut s so that each slice is cut cut in two. Also we give an application to the ontinuum: the plane is different (not homeomorphic) 3 dimensional space. This is part of a beginner's course on Algebraic Topology, given by Assoc Prof NJ Wildberger of UNSW.**Swan Homeomorphisms**Two object are called homeomorphic if they can be bi-continuosly deformed into each other. Here two swans are defromed together with their mirrorimages. The result is a torus for one swan and the union of two tori for the other. It is a deep topological theorem that these two can not be bi-continuously deformed into each other. Remark: The by-continuous deformation in this clip only starts after the one swan has put its beak under its feathers. Touching parts of a space that did not touch is NOT a bi-continuous deformation. This video was produced for a topology course at the Leibniz Universitat Hannover.**AlgTop14b: The Ham Sandwich theorem and the continuum (cont.)**We discuss the Borsuk-Ulam theorem concerning a continuous map from the sphere to the plane, and the Ham Sandwich theorem. One application is to show that the two dimensional and three dimensional affine spaces are not homeomorphic. This is the second video in the 14th lecture of this beginner's course in Algebraic Topology, given by Assoc Prof NJ WIldberger at UNSW.**AlgTop2f: Homeomorphism and the group structure on a circle (last)**This is the sixth and final video of the second lecture in this beginner's course on Algebraic Topology. We give the basic definition of homeomorphism between two topological spaces, and explain why the line and circle are not homeomorphic. Then we introduce the group structure on a circle, or in fact a general conic, in a novel way. This gives a gentle intro to the definition of a group. It also uses Pascal's theorem in an interesting way, so we give some background on projective geometry.**Non-homeomorphic Topological Spaces**This clip shows two non homeomorphic topological spaces (a line segment and a circle). Proof: We have to show that there is no bi-continuos map from the line segment to the circle. If there was such a map we could remove a point of the line segment and the image of this point on the circle. The remaining pieces would then still be homeomorphic. On the other hand the first one has two components while the second one is still connected. Since connectedness is preserved by bi-continous maps we obtain a contradiction. Therefore a bi-continous map from the line to the circle can not exist. qed This Video was produces for a topology seminar at the Leibniz Universitaet Hannover. www-ifm.math.uni-**The fundamental Group of the Torus is abelian**This video illustrates the proof of the Theorem in the title. The proof goes like this: Consider a rectangle. Then the path going up the left side of the rectangle and then along the top is homeomorphic to the path going first along the bottom and then up the right side. Gluing the rectancle to make a torus, this shows that going first around through the hole and then along the outside is homeomorphic to going first along the outside and then through the hole. Since these two path generate the fundamental group of the torus this proves that this group is abelan. qed Remark: This is a very special property. Many topological spaces have nonabelian fundamental groups. This video was produces for a topology seminar at the Leibniz Universitaet Hannover. www-ifm.math.uni-**The Alexander Sphere**A path that is homoemorphic to a circle devides a compactified plane into two pieces (inside and outside). Arthur Schönflies proved in 1906 that in this situation the inside and outside are homoemorphic. To prove a similar statement in 3 dimensions was an open problem for many years. It was solved by James Alexander in 1928 who constructed the Alexander "Horned" Sphere, as illustrated in this video. The Alexander horned sphere is a topological space which is homeomorphic to a sphere, but inside and outside are not homeomorphic. This proves that there is no ***og of Schönflies Theorem in three dimensions.

An moreover they leave distinctive topological scars as memories of their path (bottom). These topological scars would then be detectable by the Aharanov Bohm effect or violations in the fermion current in those regions.
