On the Co-Localization, Co-Support and Co-Associated Primes
of Local Homology Modules
Nguyen Tu Cuong and Tran Tuan Nam
Abstract.
Let M be a linearly compact R-module. We show in this note that
the co-localization (with respect to a multiplicative set S) Hom_R(R_S;M)
commute with local homology modules H_i^I(M). Moreover, the
set of co-associated primes Coass(H_i^I(M)) is finite if M
is a semi-discrete linearly R-module and H_j^I(M) is Artinian for all 0
\not= j < i..
