Abstract
Let R=k[x1,â¦,xn] be a polynomial ring over a prefect field of positive characteristic. Let I be an equi-dimensional ideal in R and let J be a generic link of I in S=R[uij]cÃr. We describe the parameter test submodule of S/J in terms of the test ideal of the pair (R,I) when a reduction of I is a complete intersection or almost complete intersection. As an application, we deduce a criterion for when S/J has F-rational singularities in these cases. We also compare the F-pure threshold of (R,I) and (S,J).
