Let \(M\) be a right \(R\)-module and \(\tau\) a preradical. We call \(M\) \(\tau\)-\(H\)-supplemented if for every submodule \(A\) of \(M\) there exists a direct summand \(D\) of \(M\) such that \((A + D)/D \subseteq \tau(M/D)\) and \((A + D)/A \subseteq \tau(M/A)\). Let \(\tau\) be a cohereditary...
