Spaces of directed paths on pre-cubical sets

Algebraic Topology 2016-05-27 v1

Abstract

The spaces of directed paths on the geometric realizations of pre-cubical sets, called also \square--sets, can be interpreted as the spaces of possible executions of Higher Dimensional Automata, which are models for concurrent computations. In this paper we construct, for a sufficiently good pre-cubical set KK, a CW-complex W(K)vwW(K)_v^w that is homotopy equivalent to the space of directed paths between given vertices vv, ww of KK. This construction is functorial with respect to KK, and minimal among all functorial constructions. Furthermore, explicit formulas for incidence numbers of the cells of W(K)vwW(K)_v^w are provided.
