Abstract

In this paper we introduce the notion of a closure map for a regular trisp. The main result states that an arbitrary regular trisp collapses onto the image of a closure map. As special cases we recover the previous results on the closure maps for posets and on the collapsibility of the complex of marked forests, and we obtain new results on quotients of complexes of disconnected graphs.
