Linear maps on real C* - algebras and related structures [PDF]

open access: yes, 2010
PhDIn this thesis we obtain new results on the structures of real C*-algebras and nonsurjective isometries between them. Some of the results have been published in [1].

Inference of a probabilistic Boolean network from a single observed temporal sequence [PDF]

open access: yes, 2007
The inference of gene regulatory networks is a key issue for genomic signal processing. This paper addresses the inference of probabilistic Boolean networks (PBNs) from observed temporal sequences of network states.

Monoids with tests and the algebra of possibly non-halting programs [PDF]

open access: yes, 2015
We study the algebraic theory of computable functions, which can be viewed as arising from possibly non-halting computer programs or algorithms, acting on some state space, equipped with operations of composition, if-then-else and while-do defined in ...

A note on idempotent semirings [PDF]

open access: yesCategories and General Algebraic Structures with Applications
For a commutative semiring $S$, by an $S$-algebra we mean a commutative semiring $A$ equipped with a homomorphism $S\to A$. We show that the subvariety of $S$-algebras determined by the identities $1+2x=1$ and $x^2=x$ is closed under non-empty colimits ...

Inferring context-sensitive probablistic boolean networks from gene expression data under multi-biological conditions [PDF]

open access: yes, 2007
In recent years biological microarrays have emerged as a high-throughput data acquisition technology in bioinformatics. In conjunction with this, there is an increasing need to develop frameworks for the formal analysis of biological pathways. A modeling

r-IDEAL IN A FRAME [PDF]

open access: yesJournal of Algebraic Systems
Recently, the concept of r-ideal was introduced in a commutative ring and also in a commutative semigroup. Here, we provide a similar definition for r-ideal in a frame and investigate someof its properties.

Quantum algorithms for testing and learning Boolean functions [PDF]

open access: yes, 2013
We discuss quantum algorithms based on the Bernstein-Vazirani algorithm for finding which input variables a Boolean function depends on. There are 2(n) possible linear Boolean functions of n input variables; given a linear Boolean function, the Bernstein-

Approximate Quantifier Elimination for Propositional Boolean Formulae [PDF]

open access: yes, 2011
This paper describes an approximate quantifier elimination procedure for propositional Boolean formulae. The method is based on computing prime implicants using SAT and successively refining over-approximations of a given formula.

Criterion for the cosemanticness of the Abelian groups in the enriched signature

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
In the present paper we give a criterion of the cosemanticness relative to the Jonsson spectrum of the model in the class of Abelian groups with a distinguished predicate.

0-Hecke Algebra Action on the Stanley-Reisner Ring of the Boolean Algebra [PDF]

open access: yesAnnals of Combinatorics, 2014
We define an action of the $0$-Hecke algebra of type A on the Stanley-Reisner ring of the Boolean algebra. By studying this action we obtain a family of multivariate noncommutative symmetric functions, which specialize to the noncommutative Hall-Littlewood symmetric functions and their $(q,t)$-analogues introduced by Bergeron and Zabrocki.
