D.13.6.25 tInitialFormPar

Usage:

tInitialFormPar(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 MINIMAL weighted order w.r.t. (1,w)
