In the lattice \(\mathbf{L}(_{R}M)\) of submodules of an arbitrary left \(R\)-module \(_R M\) four operation were introduced and investigated in the paper [3]. In the present work the approximations of inverse operations for two of these operations (for \(\alpha\)-product and \(\omega\)-coproduct) ...
