Homology groups of simplicial complements: A new proof of Hochster theorem
Jun Ma, Feifei Fan, Xiangjun Wang
In this paper, we consider homology groups induced by the exterior algebra generated by a simplicial compliment of a simplicial complex . These homology groups are isomorphic to…

Simplicial (co)homeology groups: New P.L. homeomorphism invariants of polyhedra
Feifei Fan, Qibing Zheng
In this paper, we define (reduced) homeology groups and (reduced) cohomeology groups on finite simpicial complexes and prove that these groups are PL homeomorphsm invariants of pol…

Moment-angle manifolds and connected sums of sphere products
Feifei Fan, Liman Chen, Jun Ma +1
This paper investigates the moment-angle manifolds whose cohomology ring is isomorphic to that of a connected sum of sphere products. We first give a example of moment-angle manifo…
