Projections and invariant means related to some Banach algebras

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 2011
The author extends a known result of \textit{M. E. B. Bekka} [Monatsh. Math. 109, No.~3, 195--203 (1990; Zbl 0713.43003)] to Banach algebras with bounded approximate identities. He investigates the case when a certain weak\(^*\)-closed subspace of \(B(A, A^*)\), where \(A\) is a left Banach \(G\)-module and \(G\) is a locally compact group, is the ...

The wonderland of reflections

open access: yes, 2017
A fundamental fact for the algebraic theory of constraint satisfaction problems (CSPs) over a fixed template is that pp-interpretations between at most countable \omega-categorical relational structures have two algebraic counterparts for their ...

A Bayesian Analogue of Gleason's Theorem

open access: yes, 2006
We introduce a novel notion of probability within quantum history theories and give a Gleasonesque proof for these assignments. This involves introducing a tentative novel axiom of probability.

A relational dataflow database [PDF]

open access: yes, 1981
A model of a relational database system based on the principles of functional, data-driven computation is proposed. Relations (sets of data tuples) are represented as streams of values carried by independent tokens among operators of an unraveling ...

Searching for an algebra on CSP solutions

open access: yes, 2021
The Constraint Satisfaction Problem (CSP) is a problem of computing a homomorphism ${\mathbf R}\to {\bf \Gamma}$ between two relational structures, where ${\mathbf R}$ is defined over a domain $V$ and ${\bf \Gamma}$ is defined over a domain $D$.

Quasi-projective relation algebras and directed cylindric algebras are categorially equivalent

open access: yes, 2013
arXiv admin note: substantial text overlap with arXiv:1303.7386, arXiv:1304.0712; and overlap with arXiv:math/0508572 by other author without ...

Born's Rule as Signature of a Superclassical Current Algebra

open access: yes, 2014
We present a new tool for calculating the interference patterns and particle trajectories of a double-, three- and N-slit system on the basis of an emergent sub-quantum theory developed by our group throughout the last years.

Projective and plane curves: a relation between algebra, topology, and complex analysis

open access: yes, 2022
Los ceros de un polinomio sobre un cuerpo algebraic revelan relaciones entre el álgebra, la topología, y el análisis complejo. Son curvas algebraicas y, en este trabajo de fin de grado, las estudiamos sobre C 2 (llamadas curvas afines) y sobre P 2 C (llamadas curvas proyectivas), haciendo especial énfasis en las curvas planas (curvas proyectivas sin ...
