Quotient Group

Quotient Group

  • mathematics

Given a Group G and a Normal Subgroup N⊴G, we define the quotient group as the set of all left-Coset of N.

G/N≡{gN∣g∈G}

Its group operation is defined as

(gN)(hN)≡(gh)N

Equivalence relation defined by N

A quotient group induces an equivalence relation upon its base group, since, by thinking about N as the set of “identity elements”, then all elements “connected” by an element of N will be equivalent.
