B-theorem
Encyclopedia
In mathematical finite group theory, the B-theorem (formerly the B-conjecture) states that if C is the centralizer of an involution
of a finite group, then every component of C/O(C) is the image of a component of C .
Involution
In mathematics, an involution, or an involutary function, is a function f that is its own inverse:-General properties:Any involution is a bijection.The identity map is a trivial example of an involution...
