Valuations and Generalized Hypersubstitutions
نویسنده
چکیده
Generalized hypersubstitutions were introduced by S. Leeratanavalee and K. Denecke as a way of making precise the concepts of strong hyperidentity and M strong hyperidentity. A variety V is called M strongly solid if every identity of V is an M strong hyperidentity. We produce a monoid M for which the k-normalized variety Nv k (V ) of an N -strongly solid variety V with respect to a valuation v is M -strongly solid.

The Order of Generalized Hypersubstitutions of Type τ=(2)
The order of hypersubstitutions, all idempotent elements on the monoid of all hypersubstitutions of type τ 2 were studied by K. Denecke and Sh. L. Wismath and all idempotent elements on the monoid of all hypersubstitutions of type τ 2, 2 were studied by Th. Changpas and K. Denecke. We want to study similar problems for the monoid of all generalized hypersubstitutions of type τ 2 . In this paper...

Received:29-10-10/Accepted:9-11-10 Abstract The concept of generalized hypersubstitutions was introduced by S. Leeratanavalee and K. Denecke in 2000. We used it as the tool to study strong hyperidentities and strongly solid varieties. In this paper we characterize all idempotent generalized hypersubstitutions of type τ = (3) and determine the order of each generalized hypersubstitution of this ...

متن کاملMulti-hypersubstitutions and Colored Solid Varieties
Hypersubstitutions are mappings which map operation symbols to terms. Terms can be visualized by trees. Hy-persubstitutions can be extended to mappings defined on sets of trees. The nodes of the trees, describing terms, are labelled by operation symbols and by colors, i.e. certain positive integers. We are interested in mappings which map differently colored operation symbols to different terms...
