摘要：

Let I be a homogeneous ideal of the polynomial ring K[x(0),...,x(n)], where K is an arbitrary field. Avoiding the construction of a minimal graded free resolution of I, we provide effective methods for computing the Castelnuovo-Mumford regularity of I that also compute other cohomological invariants of K[x(0),...,xn]/I.
