The examine of permutation teams has constantly been heavily linked to that of hugely symmetric constructions. The gadgets thought of listed below are countably endless, yet have in simple terms finitely many various substructures of any given finite measurement. they're accurately these buildings that are made up our minds by way of first-order logical axioms including the idea of countability.

Semigroups called here intra-quasiregular (known also as semisimple semigroups) were from various aspects investigated by W. D. Munn in [12], 1955, and G. Szdsz in [15], 1974. G. Szdsz in [16, 171, 1976, studied left, right and intra-reproduced elements and semigroups, whereas S. Lajos and G. SzQz in [ll],1975, investigated the so-called ( p ,q, r)-regularity. All types of the regularity of semigroups determined by equations of the form a = amzan, with m, n 2 0 , m+n 2 2, were studied by R. Croisot in [8], 1953, who proved that any of them is equivalent to the regularity, left, right or complete regularity (see the book by Clifford and Preston [7], Sect.

Every element of S is decomposable). S if B S B For undefined notions and notations we refer t o the books [l]and [9]. Next we prove several auxiliary assertions. 1. Let a semigroup S be a semilattice Y of semigroups S,, a E Y . If S satisfies anyone of the regularity conditions from Figure 3, then S, satisfies the same condition, for every 0 E Y . Figure 3. Proof. We will prove only the assertion concerning the condition (( c = zcycz)). The remaining cases can be proved similarly. Let S satisfies the condition (( c = zcycz)) and let a E Y be an arbitrary element.
