摘要：

We obtain a linear algebra data presentation of the category SHc(X, delta) of sheaves constant along the perverse simplices on a finite simplicial complex X. We also establish Koszul duality between SHc(X, delta) and the category M-c(X, delta) of perverse sheaves constructible with respect to the triangulation.
