Let \(R\) be a commutative ring, \(M\) an \(R\)-module whose zero module has a primary decomposition, \(E\) an \(R\)-module injective relative to \(M\), and \(F\) a flat \(R\)-module. The paper studies the attached primes of \(\Hom_R(M,E)\) and the weakly associated primes of \(F\otimes_R M\) in the case \(E\) and \(F\) satisfy some extra conditions.
