Suppose I have K.<t> = PowerSeriesRing(GF(2), 't') R.<x,y> = PolynomialRing(K, 'x, y')
and elt is an element of t. How do I obtain the coefficient of t in elt? Do I have to implement a coercion from R to PowerSeriesRing(PolynomialRing(GF(2), 'x, y'), 't')? Also, assuming that the degree of t in elt is actually bounded, how can I turn elt into an element of PolynomialRing(GF(2), 'x, y, t')? I tried various versions of substitute() without success. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
