Lattices of choice functions and consensus problems

open access: yes, 2004
. In this paper we consider the three classes of choice functionssatisfying the three significant axioms called heredity (H), concordance (C) and outcast (O).

Morita equivalence for partially ordered monoids and po-Γ-semigroups with unities [PDF]

open access: yes, 2014
We prove that operator pomonoids of a po-Γ-semigroup with unities are Morita equivalent pomonoids. Conversely, we show that if L and R are Morita equivalent pomonoids then a po-Γ-semigroup A with unities can be constructed such that left and right ...

On Diagonal Acts of Monoids [PDF]

open access: yes, 2007
In this paper we discuss what is known so far about diagonal acts of monoids. The first results that will be discussed comprise an overview of some work done on determining whether or not the diagonal act can be finitely generated or cyclic when looking ...

Unitary posets and amalgamations of pomonoids

open access: yes, 2014
In 1927, Schreier proved that amalgams of groups are always embeddable in the category of groups. However, this is not true in the category of semigroups, as shown by Kimura.

Posets of h-vectors of standard determinantal schemes [PDF]

open access: yes, 2015
We study the combinatorial structure of the poset H consisting of h-vectors of length s of codimension c standard determinantal schemes, defined by the maximal minors of a t × (t + c − 1) homogeneous, polynomial matrix.

Rees coextensions of finite tomonoids and free pomonoids [PDF]

open access: yes
A totally ordered monoid, or tomonoid for short, is a monoid endowed with a compatible total order. We reconsider in this paper the problem of describing the one-element Rees coextensions of a finite, negative tomonoid S, that is, those tomonoids that ...

The Partition Lattice in Many Guises [PDF]

open access: yes, 2017
This dissertation is divided into four chapters. In Chapter 2 the equivariant homology groups of upper order ideals in the partition lattice are computed. The homology groups of these filters are written in terms of border strip Specht modules as well as

Collaborations in Service Engineering:: Modeling, Analysis and Execution [PDF]

open access: yes, 2008
The development of distributed reactive systems is a complex and error-prone process. These systems consist of many separate autonomous components that operate concurrently and continuously interact with each other and with the environment in order to ...

Morfismidest kokorrutiste vahel järjestatud ja additiivsel juhul [PDF]

open access: yes, 2013
In mathematics morphisms between various structures are often studied. In particular, the endomorphisms of a structure can be of interest. The collection of endomorphisms of a given structure is a monoid.
