Monomials#

sage.rings.monomials.monomials(v, n)[source]#

Given two lists v and n, of exactly the same length, return all monomials in the elements of v, where variable i (i.e., v[i]) in the monomial appears to degree strictly less than n[i].

INPUT:

  • v – list of ring elements

  • n – list of integers
