%0 Journal Article %T Constructible sheaves on simplicial complexes and Koszul duality %A Maxim Vybornov %J Mathematics %D 1998 %I arXiv %X We obtain a linear algebra data presentation of the category of constructible with respect to perverse triangulation sheaves on a finite simplicial complex. We also establish Koszul duality between the above mentioned category and the category of perverse sheaves constructible with respect to the triangulation %U http://arxiv.org/abs/math/9802096v1
