A global view of residues in the torus

[摘要] We study the total sum of Grothendieck residues of a Laurent polynomial relative to a family f(1), ..., f(n) of sparse Laurent polynomials in n variables with a finite set of common zeroes in the torus T = (C*)(n). Under appropriate assumptions we may embed T ina toric variety X in such a way that the total residue may be computed by a global object in X, the toric residue. This yields a description of some of its properties and new symbolic algorithms for its computation. (C) 1997 Elsevier Science B.V.
