Unit representation

From Encyclopedia of Mathematics
Jump to: navigation, search

The one-dimensional representation of a group $G$ that maps each element of $G$ to the number 1. More generally, the unit representation of a group $G$ in a vector space $E$ is the representation of $G$ that maps each element of $G$ to the identity operator in $E$. The unit representation is sometimes also called the trivial representation.
