Robert S. Sheldon,Satish R. RajIn this chapter we explain constructive methods for computing the cohomology of a sheaf on a projective variety. We also give a construction for the Beilinson monad, a tool for studying the sheaf from partial knowledge of its cohomology. Finally, we give some examples illustrating the use of the Beilinson monad.

Monomial IdealsMonomial ideals form an important link between commutative algebra and combinatorics. In this chapter, we demonstrate how to implement algorithms in . for studying and using monomial ideals. We illustrate these methods with examples from combinatorics, integer programming, and algebraic geometry.
