normalizer (plural normalizers)

1. One who or that which normalizes, fits to a norm or standard etc.
2. (algebra) The subset of elements of some group which leave some given subset invariant when conjugating it.

   In symbols, the normalizer of some subset ${\displaystyle S}$ of group ${\displaystyle G}$ is the subset ${\displaystyle N(S)=\{g\in G|g^{-1}Sg=S\}}$, so that ${\displaystyle S}$ would be a normal subgroup if ${\displaystyle N(S)}$ were the whole group.
