New functions are added to for (u,v)-strict resolutions. Ord_w_m(f,w,m) (ord_w<m>) returns the order of f with respect to w for the shift vector m. Init_w_m(f,w,m) returns the initial of f with respect to w for the shift vector m. Sinit_w(resmat,w) returns the initial of the complex resmat. test17() and test18() check the (-w,w)-strictness of our minimal resolution.

ScheckIfSchreyer(): it checks if grade (grading function) is module1v (grading without vector component). Note that ring_of_differential_operators switches grade to module1. Found a reason why the strategy fails. It is because the schreyer skelton contains an element of the form [1,f]. This bug will be fixed soon. A list of todo (e.g., init<m> ) Succeeded to construct the V-minimal resolution for 1/(x^3+y^3+z^3). The betti numbers are 4,5,2.

Bug fix of Sminimal(). test_ann3(f) computes the V-minimal free resolution for the laplace transform of the annihilating ideal 1/f. It also checks if the obtained one is exact or not by using IsExact_h(). Sminimal() still contains troubles. For example, it does not work for [x^2+y^2, x*y] with (-1,-1,1,1) weight vector.

I've been quiet and developed a code to construct minimal free
resolution in D. This is a first working version for the minimal
free resolution. It is written in the language kan/k0 and can be
compiled into sm1 code. The language kan/k0 is similar to asir with
extension of "class".
Sample:
k0
load["minimal.k"];
a = Sminimal(v);
