Exempel på hur du använder COSETS i en mening

• For a congruence relation on a group, the equivalence class of the identity element is always a normal subgroup of the original group, and the other equivalence classes are precisely the cosets of that normal subgroup.
• Every subgroup of index 2 is normal: the left cosets, and also the right cosets, are simply the subgroup and its complement.
• However, some authors (including Dummit & Foote and Rotman) reserve this notation specifically for representing the quotient group formed from the cosets in the case where H is a normal subgroup of G.
• Because G is the disjoint union of the left cosets and because each left coset has the same size as H, the index is related to the orders of the two groups by the formula.
• This is sometimes unavoidable when the arguments are cosets and when the equation refers to coset representatives.
• The Bruhat decomposition G = BWB of a semisimple algebraic group into double cosets of a Borel subgroup can be regarded as a generalization of the principle of Gauss–Jordan elimination, which generically writes a matrix as the product of an upper triangular matrix with a lower triangular matrix—but with exceptional cases.
• In mathematics, coset enumeration is the problem of counting the cosets of a subgroup H of a group G given in terms of a presentation.
• They demonstrate that this topology is linked to certain cosets of the pure braid group in the full braid group, as well as the centralizers of elements within the corresponding coset.
