This paper lays the foundations of a combinatorial homotopy theory, called A-theory, for simplicial complexes, which reflects their connectivity properties. A collection of bigraded groups is constructed, and methods for computation are given. A Seifert-Van Kampen type theorem and a long exact seque

We construct two-dimensional Buchsbaum complexes with certain lower bounds on the f -vectors (or equivalently h-vectors) of Buchsbaum complexes obtained by Terai [8].
