Retract
In mathematics, in the field of group theory, a subgroup of a group is termed a retract if there is an endomorphism of the group that maps surjectively to the subgroup and is identity on the subgroup. In symbols, H is a retract of G if and only if there is an endomorphism such that σ = h for all and for all . The endomorphism itself is termed an idempotent endomorphism or a retraction. The following is known about retracts: ⁕A subgroup is a retract if and only if it has a normal complement. The normal complement, specifically, is the kernel of the retraction. ⁕Every direct factor is a retract. Conversely, any retract which is a normal subgroup is a direct factor. ⁕Every retract has the congruence extension property. ⁕Every regular factor, and in particular, every free factor, is a retract.
