- W1480991250 abstract "A module $M$ is called H-supplemented if for every submodule $A$ of $M$ there is a direct summand $A'$ of $M$ such that $A+X=M$ holds if and only if $A'+X=M$ for any submodule $X$ of $M$. (Equivalently, for each $Xleq M$, there exists a direct summand $D$ of $M$ such that $(X+D)/Dll M/D$ and $(X+D)/Xll M/X$.) Direct summands and sums of H-supplemented modules are studied and a question posed by Mohamed and Muller in 1990 is answered in the negative." @default.
