... for E as y 2 = x3 + Ax + B = f (x), the first case occurs when f (x) has one real root, and the second case occurs when f (x) has three real roots. With everything in place, we are now ready to tackle the structure of infinite, closed subgroups in 1-dimensional, compact Lie groups. The following the ...

... cosets of n Z (nZ, 1+n Z, …) are the residue classes modulo n. Note: Here is how to compute in a factor group: We can multiply (add) two cosets by choosing any two representative elements, multiplying (adding) them and finding the coset in which the resulting product (sum) lies. Example: in Z/5Z, we ...

Congruence lattice problem

In mathematics, the congruence lattice problem asks whether every algebraic distributive lattice is isomorphic to the congruence lattice of some other lattice. The problem was posed by Robert P. Dilworth, and for many years it was one of the most famous and long-standing open problems in lattice theory; it had a deep impact on the development of lattice theory itself. The conjecture that every distributive lattice is a congruence lattice is true for all distributive lattices with at most ℵ1 compact elements, but F. Wehrung provided a counterexample for distributive lattices with ℵ2 compact elements using a construction based on Kuratowski's free set theorem.
