FThresholds :: muList

muList -- computes a list of mu-values associated to a given F-threshold or F-pure threshold

Synopsis

Description

Given an ideal I in a polynomial ring k[x1,...,xn], this function computes mu(d, I, J) or mu(d,f,J) recursively for d = 0,...,e. In other words, calling muList is the same as calling nuList with the option ComparisonTest set to FrobeniusPower.

i1 : R = ZZ/3[x,y];
i2 : I = ideal(x^2, x+y);

o2 : Ideal of R
i3 : J = ideal(x, y^2);

o3 : Ideal of R
i4 : muList(2,I,J)

o4 = {1, 5, 17}

o4 : List
i5 : muList(3,I)

o5 = {0, 2, 8, 26}

o5 : List
i6 : muList(3,x^3+y^3,J)

o6 = {0, 1, 5, 17}

o6 : List
