Occurrence of the introduced alga Caulerpa ollivieri Dostál, 1929 [Caulerpaceae, Chlorophyta] in the Southern Gulf of Mexico
This work reports the occurrence of the introduced alga Caulerpa ollivieri Dostál, 1929 in the Southern Gulf of Mexico off the northern coast of the Yucatan Peninsula, Mexico. In 2010, a specimen was collected off the ... -

Octopus maya parasites off the Yucatán Peninsula, Mexico. I. Faunal assemblages
The red octopus Octopus maya Voss et Solís-Ramírez, 1966 is an endemic species found exclusively off the coast of the Yucatán Peninsula, Mexico; its fishery is one of the most important along the Atlantic coast of Mexico ... -

Octopus maya parasites off the Yucatán Peninsula, Mexico. II. Salivary gland damage by cestodes
The red octopus Octopus maya Voss et Solís-Ramírez, 1966 is an endemic species and one of the most important fishery resources of the Yucatán Peninsula, Mexico. Due to its economic importance and the fact that in recent ... -

On almost simple transcendental field extensions
We study some properties of almost simple transcendental field extensions in order to analyze the endomorphisms ring of algebraically bounded Λ−modules where Λ is a semigenerically tame finite-dimensional k−algebra, k a ... -
On centrally generically tame algebras over perfect fields
We show that the central generic tameness of a finite-dimensional algebra Λover a (possibly finite) perfect field, is equivalent to its non-almost sharp wildness. In this case: we give, for each natural number d, ... -
On permutation polynomials over local finite commutative rings
In this paper, we give criteria for a polynomial to be a permutation polynomial of a local finite commutative ring with identity. These criteria generalize known results established for finite fields. On the other hand, ... -
On restrictions of generic modules of tame algebras
Given a convex algebra Λ0 in the tame finite-dimensional basic algebra Λ, over an algebraically closed field, we describe a special type of restriction of the generic Λ-modules. -
On semigeneric tameness under base field extension
The notions of central endolength and semigeneric tameness are introduced, and their behaviour under base field extension for finite-dimensional algebras over perfect fields are analysed. For k a perfect field, K an ... -

On the connection between the representation type of an algebra and its lattice of preradicals
In this paper, we study lattices of preradicals which are not small classes (in which case we say that the corresponding rings are p-large), and specially we consider some infinite representation type algebras. We construct ... -
