We construct CW spheres from the lattices that arise as the closed sets of a convex closure, the meet-distributive lattices. These spheres are nearly polytopal, in the sense that t...

In this paper we are concerned with the following question: for a semigroup S, what is the largest size of a subsemigroup T S where T has a given property? The semigroups S that w...
We propose String MultiSet Rewriting (SMSR) as an intermediate language for simulation of biomolecular systems. Higher level formalisms for biological systems description can be t...

An acyclic coloring of a graph G is a proper coloring of the vertex set of G such that G contains no bichromatic cycles. The acyclic chromatic number of a graph G is the minimum nu...
We present a decomposition-based approach to managing probabilistic information. We introduce world-set decompositions (WSDs), a space-efficient and complete representation system ...
