Mathematics. 1. the integral part of a logarithm.the integral part of a logarithm. 2. let R be a ring (or integral domain or field). If there is a least positive integer n such that na = 0 for all a R, then R is said to have characteristic n. If no such n exists, R is said to have characteristic 0. Denoted char R = n.let R be a ring (or integral domain or field). If there is a least positive integer n such that na = 0 for all a R, then R is said to have characteristic n. If no such n exists, R is said to have characteristic 0. Denoted char R = n. 3. a subgroup H of a group G is said to be a characteristic subgroup if f(H) is a subgroup of H for every automorphism f: G G. If f is an endomorphism then H is said to be fully invariant. Every fully invariant subgroup is characteristic and every characteristic subgroup is normal.a subgroup H of a group G is said to be a characteristic subgroup if f(H) is a subgroup of H for every automorphism f: G G.
