Test if the given polynomial is in the multiplier ideal for given ideal and coefficient. In general, the test is cheaper than computing the whole multiplier ideal.
There are two options for strategy:i1 : R = QQ[x_1..x_4]; |
i2 : isInMultiplierIdeal(x_1, ideal {x_1^3 - x_2^2, x_2^3 - x_3^2}, 31/18) o2 = false |
i3 : isInMultiplierIdeal(x_1*x_2, ideal {x_1^3 - x_2^2, x_2^3 - x_3^2}, 31/18) o3 = true |
