Zero Module


The zero module over a ring R consists of a single zero element 0, with addition given by

 0+0=0,

and multiplication by any element a of R given by

 a·0=0.

The set {0} is closed under both module operations. It also deserves the name trivial module, since it is the simplest module possible.
