Example of C-rigid polytopes which are not B-rigid

Algebraic Topology 2017-06-13 v1 Combinatorics

Abstract

A simple polytope PP is said to be \emph{B-rigid} if its combinatorial structure is characterized by its Tor-algebra, and is said to be \emph{C-rigid} if its combinatorial structure is characterized by the cohomology ring of a quasitoric manifold over PP. It is known that a B-rigid simple polytope is C-rigid. In this paper, we, further, show that the B-rigidity is not equivalent to the C-rigidity.
