D.13.3.27 tInitialFormParMax

Usage:

tInitialFormParMax(f,w); f a polynomial, w an integer vector

Assume:

f is a polynomial in Q(t)[x_1,...,x_n] and w=(w_1,...,w_2)

Return:

poly, the t-initialform of f(t,x) w.r.t. (-1,w) evaluated at t=1

Note:

the t-initialform are the terms with MAXIMAL weighted order w.r.t. (1,w)
