A Structural Approach to the Locality of Pseudovarieties of the Form LH (m) V
نویسنده
چکیده
We show that if H is a Fitting pseudovariety of groups and V is a local pseudovariety of monoids, then LH ©m V is local if either V contains the six element Brandt monoid, or H is a non-trivial pseudovariety of groups closed under extension.

Locality of Ds and Associated Varieties
We prove that the pseudovariety DS, of all nite monoids each of whose regular D-classes is a subsemigroup, is local. (A pseudovariety (or variety) V is local if any category whose local monoids belong to V divides a member of V). The proof uses the \kernel theorem" of the rst two authors together with the description by P. Weil of DS as an iterated \block product". The one-sided analogues of th...
متن کاملFree Profinite Semigroups Over Some Classes of Semigroups Locally in D(G)
The theory of free profinite semigroups, which received its major impetus with the publication of Reiterman’s paper [17] in the early eighties, has proven to be an important tool in the study of pseudovarieties of semigroups and on the varieties of recognizable languages associated with them (via Eilenberg’s Theorem on varieties [13]). The importance of Reiterman’s theorem was immediately under...
متن کاملClosed-form solution for peak crushing force of the S-rails
One of the most important structural components of engine compartment assembly in a car body is the Srail. S-rails has significant role in absorbing energy during crash events and therefore it is designed for efficient behavior in such conditions. Driving the peak crushing force of the S-rails is one of the important objectives in the design process of such structures. Peak crushing force is ex...
متن کاملMyxobolus spp. (Myxosporea: Myxobolidea) from fishes of the Zayandeh-Rud River (Esfahan, Iran); new hosts and locality record
In a parasitic survey of the native and introduced fishes in the Zayandehrud River, 5 Myxobolus spp. were found in the gills, fins and skin of examined fish specimens. They include M. varicorhini from fin and M. samgoricus from skin of Capoeta damascina, M. musajevi from gills of Capoeta capoeta gracilis, Myxobolus cristatus from Capoeta aculeata, and M. saidovi from Alburnus sp. Data on the lo...
