The hull-kernel topology on prime ideals in posets

prime ideals P(Q) , minimal prime ideals Min (Q) and maximal ideals Max (Q Min (Q) of a poset Q. Under the additional assumption that every maximal ideal is prime, the collection of all maxim...

Endomorphism rings with finitely many maximal right ideals.

We show that finite direct sums of modules whose endomorphism rings have only finitely many maximal right ideals and also direct summands of these sums are described by a structure of simple hypergraphs. Vertices of this hypergraph ...

A Categorial Contribution to the Kummer Theory of ideal numbers

The main result of this article is the description of all maximal delta-categories by means of alpha-ultrapseudofilters. A delta category is a subcategory of the category of all semigroups possessing a divisor theory in the sence of Arnold. ...

A Categorical Contribution to the Kummer Theory of Ideal Numbers

The main result is the description of all maximal delta 1-categories by means of alfa-pseudofilters. A delta 1 - category is a subcategory of the category of all semigroups possessing a divisor theory with less morphisms such that this divis...

Closed ideals of operators on the Tsirelson and Schreier spaces

that the lattice of closed ideals of B(X) has a very rich structure, in particular B(X) contains at least continuum many maximal ideals. Our approach is to study the closed ideals generated by the basis projection...

On n-normal posets

A poset is called n-normal if every its prime ideal contains at most n minimal prime ideals. In the paper some properties and characterizations of n-normal posets are obtained....

Relationship between entropy and SNR changes in image enhancement

are traditionally tuned by maximization of SNR criterion, which is unfortunately based on the knowledge of an ideal image. Our approach is based on Hartley entropy, its estimation, and differentiation. Resulting gradient of entropy...

Indestructibility of ideals and MAD families

In this survey paper we collect several known results on destroying tall ideals on countable sets and maximal almost disjoint families with forcing. In most cases we provide streamlined proofs of the presented results. The paper con...
