WebThe quotient group G/N is a group under the operation (gN)(hN) = ghN, and is isomorphic to a subgroup of the group of permutations of the cosets of N in G. Normal subgroups play a fundamental role in the theory of groups. For example, they allow us to study the structure of a group by considering the quotient group G/N.

These are … Webcosets in general are the lines parallel to H. Two parallel lines are either equal or disjoint, so each pair of H-cosets is either equal or disjoint. In Figure1, the H-cosets of v and v0 are equal while those of v and w are disjoint. x y H v+ H= v0+ H w+ H v v0 w Figure 1. The cosets of Re 1 in R2. Example 2.2.

WebAn equivalence relation ~ on a set X requires three things: . a ~ a for all a in X (reflexive); . if a ~ b, then b ~ a (symmetric); . if a ~ b and b ~ c, then a ~ c (transitive).. In plain language, the reflexive property says that every object in X is equivalent to itself. The symmetric property says that equivalence doesn't care about order.
