Semirings of positive elements (GA201/98/P247)

Simple commutative semiring with cancellative addition but no neutral element can be represented as a semiring of positive elements of a partially ordered subfield of real numbers with weakened order. If moreover such a semiring...

Structure of commutative semirings (GP13-29835P)

The subject of the project is studying the structure of commutative semirings commutative semirings for the biggest possible generating sets, especially of semirings of the reals and to a deepening of the results regarding ...

Nonassociativity and multilinearity (GA201/09/0296)

subgroups of the Monster. We anticipate that semirings will find applications important structural problems in the theory of semirings. In this context we shall also investigate applications of semirings in cryptography. W...

Algebraic methods in automata and formal language theory (GA201/06/0936)

The project is aimed to develop algebraic methods in formal language theory. In particular, we will further investigate classes of syntactic structures of regular languages like (ordered) syntactic monoids, syntactic semirings, syntactic hom...

Function algebras and ordered structures related to logic and data fusion (8J19AT023)

theory of classical structures like rings, semirings, near-rings etc., we aim to find connections among these structures. In particular, we intend to classify which semirings into semiring-like algebras. (Chajda, Doležalov...

Supervisory control of large distributed discrete event systems (KJB100190609)

This project aims at studying logical and timed discrete event systems using methods from universal coalgebra and idempotent algebra with special focus on supervisory control of large distributed systems. Methods of idempotent algebra enable linear r...

Continuous systems with synchronization and linear integral equations with special kernels (IAC1019007)

Algebraic approach to the study of discrete event systems with the synchronization phenomenom consists in the application of idempotent semirings, called dioids. The linear description using dioid algebras allowed to obtain important results...

Functional equations in special function spaces (GA201/99/D081)

In the last years, new approaches to the study of discrete non-linear systems, based on the use of special algebraic structures, have appeared. For instance, the use of the idem potent semiring (dioid) called (min,+) algebra leads to a linea...
