DESCRIPTION:Two countable discrete groups $G$ and $H$ are said to be measu
 re equivalent\, or ME in short\, if there is a standard measure space whic
 h carries commuting measure-preserving actions of $G$ and $H$ such that ea
 ch of actions has a fundamental domain of finite measure. For example latt
 ices of a locally compact group are ME to each other. The notion of measur
 e equivalence is introduced by Gromov as a younger brother of quasi-isomet
 ry for groups. I will give a survey on ME embeddings. \n
