In abstract algebra, a normal subgroup is a subgroup which is invariant under conjugation by members of the group of which it is a part. In other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.Normal subgroups (and only normal subgroups) can be used to construct quotient groups from a given group.n other words, a subgroup H of a group G is normal in G if and only if gH = Hg for all g in G, i.e., the sets of left and right cosets coincide.
For example, the y-axis is normal to the curve y = x2 at the origin. However, normal may also refer to the magnitude of a vector. In particular, a set is called orthonormal (orthogonal plus normal) if it is an orthogonal set of unit vectors. As a result, use of the term normal to mean orthogonal is often avoided.The word normal also has a different meaning in probability and statistics. A vector space with a bilinear form generalizes the case of an inner product. When the bilinear form applied to two vectors results in zero, then they are orthogonal.The case of a pseudo-Euclidean plane uses the term hyperbolic orthogonality.he word normal also has a different meaning in probability and statistics.
