Self-Rectangulating Varieties of Type 5
We show that a locally finite variety which omits abelian types is self–rectangulating if and only if it has a compatible semilattice term operation. Such varieties must have type–set {5 }. These varieties are residually small and, when they are finitely generated, they have definable principal congruences. We show that idempotent varieties with a compatible semilattice term operation have the ...

متن کاملVarieties of Self-Reference
The significance of any system of explicit representation depends not only on the immediate properties of its representational structures, but also on two aspects of the attendant circumstances: implicit relations among, and processes defined over, those individual representations, and larger circumstances in the world in which the whole representational system is embedded. This relativity of r...

where the subscripts are reduced modulo n, and r ≥ 2, n ≥ 2. We also denote in short the above presentation by F (r, n, s, p) = Gn(x1x1+p · · ·x1+p(r−1)x 1+s) according to notation in [13] and [16]. This family contains many classes of cyclic presentations of groups, previously considered by several authors. The groups F (2, n, 2, 1) are the Fibonacci groups F (2, n) = Gn(x1x2x 3 ) introduced b...
