Let Φ 1: Σ →Σ and Φ 2: Σ →Σ be two homeomorphisms. Then Φ 1 is an isotopic homeomorphism to Φ 2 if and only if Φ 1(C i) is isotopic to Φ 2(C i) for all i = 1,...,n. Note that if we have a polygonal representation of the surface Σ, in Alexander’s Lemma

Web6 nov. 2024 · The Sierpinski Carpet is a plane fractal curve i.e. a curve that is homeomorphic to a subspace of plane. It was first described by Waclaw Sierpinski in 1916. In these type of fractals, a shape is divided into a smaller copy of itself, removing some of the new copies and leaving the remaining copies in specific order to form new shapes … WebMotivated by a wealth of powerful field-theoretically-inspired 4-manifold invariants [15, 32, 36, 51], a major open problem in quantum topology is the construction of a four-dimensional topological field theory in the sense of Atiyah-Segal [1, 45] which is sensitive to exotic smooth structure.In this paper, we prove that no semisimple topological field theory …
