The purpose of this chapter is to illustrate how bigraded commutative algebra differs from the classical graded case and to indicate some of the theoretical tools needed to understand free resolutions in the bigraded case. Bigraded commutative algebra is a special case of multigraded commutative algebra, which is in turn an instance of toric (or polytopal) algebra.
