A Generalization of Seifert-Van Kampen Theorem for Fundamental Groups

Linfan Mao

As we known, the {\it Seifert-Van Kampen theorem} handles fundamental groups of those topological spaces $X = U \cup V$ for open subsets $U, V \subset X$ such that $U \cap V$ is arcwise…

Combinatorial Structure of Manifolds with Poincaré Conjecture

Linfan Mao

A manifold $M^{n}$ inherits a labeled $n$ -dimensional graph $M [G^{L}]$ structure consisting of its charts. This structure enables one to characterize fundamental groups of…
