蕴涵顶点可分解性的f-向量
f-vectors implying vertex decomposability
摘要:
证明了如果一个d维n面纯单纯复形在所有d维n面复形中具有最少的(d-1)维面,则它是顶点可分解的.这回答了赫尔佐格和T.日比事实上,我们证明了他们的定理使用组合方法的推广。
英文摘要:
We prove that if a pure simplicial complex of dimension d with n facets has the least possible number of (d-1)-dimensional faces among all complexes with n faces of dimension d, then it is vertex decomposable. This answers a question of J. Herzog and T. Hibi. In fact we prove a generalization of their theorem using combinatorial methods.
