On linear equivalence of the P-adic and P-symbolic topologies
Abstract
AbstractExamples are given of subrings of k[x,y] and prime ideals in these subrings for which the ideal-adic and ideal-symbolic topologies are linearly equivalent while the powers are not primary. We also generalize a theorem of Huneke concerning the condition l(PRQ) < ht(Q) for all Q properly containing P
