Description
This function computes the integral closure of a monomial ideal I=(f1,...,fm)⊂R in the polynomial ring R[t] and the normalization of its Rees algebra. The normalization of the Rees algebra is the integral closure of R[f1t,...,fmt] in R[t]. For a definition of the Rees algebra (or Rees ring) see Bruns and Herzog, Cohen-Macaulay rings, Cambridge University Press 1998, p. 182.
