## Distributively generated rings and distributive modules

### Mathematical Notes (2000-10-01) 68: 488-495 , October 01, 2000

A module is said to be distributively generated if it is generated by distributive submodules. We prove that the endomorphism ring of a finitely generated projective right module over a right distributively generated ring is a right distributively generated ring. If*M* is a module over a ring*A* and*A/J(A)* is a normal exchange ring, then*M* is a distributive module⇔*M* is a Bezout module.

### Mathematical Notes (1995-10-01) 58: 1100-1116 , October 01, 1995

By a distributive module we mean a module with a distributive lattice of submodules.

Then*B* is a left distributive ring, and*H* coincides with the set of all nilpotent elements of*A*.
