Partial translation algebras for trees

open access: yesJournal of Noncommutative Geometry, 2009
In [1] we introduced the notion of a partial translation C*-algebra for a discrete metric space. Here we demonstrate that several important classical C*-algebras and extensions arise naturally by considering partial translation algebras associated with subspaces of trees.

Cluster algebras of infinite rank [PDF]

open access: yes, 2014
Holm and Jørgensen have shown the existence of a cluster structure on a certain category D that shares many properties with finite type A cluster categories and that can be fruitfully considered as an infinite analogue of these. In this work we determine

Algebras for parameterised monads [PDF]

open access: yes, 2009
Parameterised monads have the same relationship to adjunctions with parameters as monads do to adjunctions. In this paper, we investigate algebras for parameterised monads. We identify the Eilenberg-Moore category of algebras for parameterised monads and

Duality for Hilbert algebras with supremum: An application [PDF]

open access: yesMathematica Bohemica, 2017
We modify slightly the definition of $H$-partial functions given by Celani and Montangie (2012); these partial functions are the morphisms in the category of $H^\vee$-space and this category is the dual category of the category with objects the Hilbert ...

Automatic Continuity of Almost Derivations on Frechet $Q$-Algebras

open access: yesCommunications in Advanced Mathematical Sciences, 2022
In 1971 R. L. Carpenter proved that every derivation on a semisimple commutative Frechet algebra with identity is continuous. The concept of almost derivations on Frechet algebras is introduced in this article. Also, R. L.

New Partial Symmetries from Group Algebras for Lepton Mixing

open access: yesAdvances in High Energy Physics, 2020
Recent stringent experiment data of neutrino oscillations induces partial symmetries such as Z2 and Z2×CP to derive lepton mixing patterns. New partial symmetries expressed with elements of group algebras are studied.

Partial corepresentations of Hopf algebras [PDF]

open access: yesJournal of Algebra, 2021
We introduce the notion of a partial corepresentation of a given Hopf algebra $H$ over a coalgebra $C$ and the closely related concept of a partial $H$-comodule. We prove that there exists a universal coalgebra $H^{par}$, associated to the original Hopf algebra $H$, such that the category of regular partial $H$-comodules is isomorphic to the category ...

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].

Modeling of Complex Systems by Means of Partial Algebras

open access: yesMendel, 2019
Complex systems are very hard to describe by some unified language and calculus. In cases when their nature is very heterogeneous is possible to use with advantage state description.

Free probability on Hecke algebras and certain group C^{*}-algebras induced by Hecke algebras [PDF]

open access: yesOpuscula Mathematica, 2016
In this paper, by establishing free-probabilistic models on the Hecke algebras \(\mathcal{H}\left(GL_{2}(\mathbb{Q}_{p})\right)\) induced by \(p\)-adic number fields \(\mathbb{Q}_{p}\), we construct free probability spaces for all primes \(p\).
