This booklet -now in its moment revised and prolonged variation -is a self-contained exposition of the idea of compact correct semigroupsfor discrete semigroups and the algebraic houses of those items. The equipment utilized within the e-book represent a mosaic of endless combinatorics, algebra, and topology. The reader will locate a variety of combinatorial functions of the speculation, together with the primary units theorem, partition regularity of matrices, multidimensional Ramsey conception, and plenty of extra.

47. Let S be a semigroup. If S has a minimal left ideal, then every left ideal of S contains a minimal left ideal. Proof. Let L be a minimal left ideal of S and let J be a left ideal of S. Pick a 2 J . 46, La is a minimal left ideal which is contained in J . 48. S/. Statements (a) through (f) are equivalent and imply statement (g). If either S is simple or every left ideal of S has an idempotent, then all statements are equivalent. (a) Se is a minimal left ideal. (b) Se is left simple. (c) eSe is a group.

43 (c), R \ J is a minimal left ideal of R. 62. Let S be a semigroup and assume that there is a minimal left ideal of S which has an idempotent. Then all minimal left ideals of S are isomorphic. Proof. Let L be a minimal left ideal of S with an idempotent e. 59 eSe is a group. est e/ 1 , where the inverses are taken in eSe. est e/ is an idempotent. S / D ¹R W R is a minimal right ideal of Sº. Pick a minimal right ideal R of S such that s 2 R. 61. est e/ 1 as claimed. Now let L0 be any other minimal left ideal of S.

A) The smallest ideal of S which contains a given element x 2 S is called the principal ideal generated by x. (b) The smallest left ideal of S which contains x is called the principal left ideal of S generated by x. (c) The smallest right ideal of S which contains x is called the principal right ideal generated by x. 33. Let S be a semigroup and let x 2 S. (a) The principal ideal generated by x is S xS [ xS [ Sx [ ¹xº. (b) If S has an identity, then the principal ideal generated by x is SxS. (c) The principal left ideal generated by x is Sx [ ¹xº and the principal right ideal generated by x is xS [ ¹xº.
