A graph theoretic approach to combinatorial problems in semigroup theory [PDF]
The use of graph theory has become widespread in the algebraic theory of semi¬ groups. In this context, the graph is mainly used as a visual aid to make presentation clearer and the problems more manageable.

We discuss the approximate controllability of fractional evolution equations involving generalized Riemann-Liouville fractional derivative. The results are obtained with the help of the theory of fractional calculus, semigroup theory, and the Schauder ...

A semigroup approach to the Gnedenko system with single vacation of a repairman [PDF]
We investigate the Gnedenko system with one repairman who can take vacations. Our main focus is on the time asymptotic behaviour of the system. Using C 0-semigroup theory for linear operators we first prove the well-posedness of the system and the ...

Throughout this paper our study focuses on transformation semigroups. These kinds of semigroups are the corner stone of semigroup theory. This is because every semigroup is isomorphic to transformation semigroup.

In den letzten Jahren haben sich namentlich die beiden Autoren wie auch J. Lawson mit möglichen Verallgemeinerungen der Lieschen Fundamentalsätze auf (lokale) Halbgruppen in Lieschen Gruppen befaßt. Dabei beginnen die Schwierigkeiten bereits bei der Eingrenzung geeigneter Klassen von Halbgruppen und der Definition passender infinitesimaler Objekte. Für

Recent developments in inverse semigroup theory
After reviewing aspects of the development of inverse semigroup theory, we describe an approach to studying them which views them as ‘non-commutative meet semilattices’.

Semigroup analysis of structured parasite populations [PDF]
Motivated by the modelling of structured parasite populations in aquaculture we consider a class of physiologically structured population models, where individuals may be recruited into the population at different sizes in general. That is, we consider a

Some remarks on the domination between conjunctions and disjunctions
There are diverse domination properties considered in linear programming, game theory, semigroup theory and graph theory. In this paper we present a class of conjunctions which dominate each triangular conorm.

Semigroups of order-decreasing transformations
Let X be a totally ordered set and consider the semigroups of orderdecreasing (increasing) full (partial, partial one-to-one) transformations of X. In this Thesis the study of order-increasing full (partial, partial one-to-one) transformations has been

Partial maps with domain and range: extending Schein's representation
The semigroup of all partial maps on a set under the operation of composition admits a number of operations relating to the domain and range of a partial map. Of particular interest are the operations R and L returning the identity on the domain of a map
