Weakly free regular semigroups I. The general case
We prove the existence of a regular semigroup F(X) weakly generated by X such
that all other regular semigroups weakly generated by X are homomorphic images
of F(X). The semigroup F(X) is introduced by a presentation and the word
problem for that presentation is solved.Comment: 23 pages; 4 figure
