For this, we use the framework of sheaves over posets. We develop a notion of gluing of posets and of sheaves over posets, which we apply to construct global resolutions for equivariant sheaves. Our constructions give a natural correspondence between resolutions for reflexive equivariant sheaves and free resolutions of vector space arrangements.preliminary version only; 48 pages, requires packages ams*, graphicx, enumerate, xy, epsfigAlgebraic GeometryCommutative AlgebraCombinatorics14M25, 18F20text
