Whitney blocks in the hyperspace of a finite graph
Let X be a finite graph. Let C(X) be the hyperspace of all nonempty subcontinua of X and let μ : C(X) → R be a Whitney map. We prove that there exist numbers 0 < T0 < T1 < T2 < · · · < TM = μ(X) such that if T ∈ (Ti−1, Ti), then the Whitney block μ(Ti−1, Ti) is homeomorphic to the product μ(T )× (Ti−1, Ti). We also show that there exists only a finite number of topologically different Whitney l...
متن کاملThe Fundamental Group
The focus of this exposition is the fundamental group of a topological space. The paper begins by defining paths and homotopy, and proceeds to construct the fundamental group. Later, attention turns to the consequences of the construction, in particular to the fundamental group of S1 and Van Kampen’s Theorem.
متن کاملThe Fundamental Group
This is the next article in a series devoted to the homotopy theory (following [11] and [12]). The concept of fundamental groups of pointed topological spaces has been introduced. Isomorphism of fundamental groups defined with respect to different points belonging to the same component has been stated. Triviality of fundamental group(s) of R n has been shown. the terminology and notation for th...
متن کاملMonoids in the fundamental group . . .
We study monoids generated by Zariski-van Kampen generators in the 17 fundamental groups of the complement of logarithmic free divisors in C listed by Sekiguchi (Theorem 1). Five of them are Artin monoids and eight of them are free abelian monoids. The remaining four monoids are not Gaußian and, hence, are neither Garside nor Artin (Theorem 2). However, we introduce, similarly to Artin monoids,...
متن کاملThe fundamental group of the clique graph
Given a finite connected bipartite graph B = (X, Y ) we consider the simplicial complexes of complete subgraphs of the square B of B and of its induced subgraphs B[X] and B[Y ]. We prove that these three complexes have isomorphic fundamental groups. Among other applications, we conclude that the fundamental group of the complex of complete subgraphs of a graph G is isomorphic to that of the cli...
