Modularity prevents tails

Keith A. Kearnes, Emil W. Kiss

We establish a direct correspondence between two congruence poroperties for finite algebras. The first property is that minimal sets of type i omit tails. The second property is th…

Self-rectangulating varieties of type 5

Keith A. Kearnes, Ågnes Szendrei

We show that a locally finite variety which omits abelian types is self-regulating if and only if it has a compatible semilattice term operation. Such varieties must have a type-se…

Bohr's power series theorem in several variables

Harold P. Boas, Dmitry Khavinson

Generalizing a classical one-variable theorem of Harald Bohr, we show that if an n-variable power series has modulus less than 1 in the unit polydisc, then the sum of the moduli of…

Projectivity and isomorphisms of strictly simple algebras

Keith A. Kearnes, Ågnes Szendrei

We describe a sufficient condition for the localization functor to be a categorical equivalence. Using this result we explain how to simplify the test for projectivity. This leads…

The relationship between two commutators

Keith A. Kearnes, Ågnes Szendrei

We clarify the relationship between the linear commutator and the ordinary commutator by showing that in any variety satisfying a nontrivial idempotent Mal'cev condition the linear…
