流形匹配复形

Manifold Matching Complexes

Margaret Bayer, Bennet Goeckner, Marija Jelić Milutinović

摘要:

图的匹配复形是单纯复形,其顶点集是图的边集,每个独立边集都有一个面。本文完全刻画了匹配复形是同调流形的偶(图,匹配复形),不论有无边界。除了二维,所有这些流形都是球面或球。

英文摘要:

The matching complex of a graph is the simplicial complex whose vertex set is the set of edges of the graph with a face for each independent set of edges. In this paper we completely characterize the pairs (graph, matching complex) for which the matching complex is a homology manifold, with or without boundary. Except in dimension two, all of these manifolds are sphere or balls.
