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 \(p\).

Decoherence-free algebra [PDF]

open access: yesPhysics Letters A, 2003
We consider the decoherence free subalgebra which satisfies the minimal condition introduced by Alicki. We show the manifest form of it and relate the subalgebra with the Kraus representation. The arguments also provides a new proof for generalized L ders theorem.

Correspondences among CFTs with different W-algebra symmetry

open access: yesNuclear Physics B, 2020
W-algebras are constructed via quantum Hamiltonian reduction associated with a Lie algebra g and an sl(2)-embedding into g. We derive correspondences among correlation functions of theories having different W-algebras as symmetry algebras.

Further results on elementary Lie algebras and Lie A-algebras. [PDF]

open access: yes, 1994
A finite-dimensional Lie algebra L over a field F of characteristic zero is called elementary if each of its subalgebras has trivial Frattini ideal; it is an A-algebra if every nilpotent subalgebra is abelian. This paper is a continuation of the study of

Free homotopy algebras [PDF]

open access: yesHomology, Homotopy and Applications, 2005
This note was originated many years ago as my reaction to questions of several people how free strongly homotopy algebras can be described and what can be said about the structure of the universal enveloping A(m)-algebra of an L(m)-algebra, and then circulated as a "personal communication." I must honestly admit that it contains no really deep result ...

Finitely generated free Heyting algebras via Birkhoff duality and coalgebra [PDF]

open access: yesLogical Methods in Computer Science, 2011
Algebras axiomatized entirely by rank 1 axioms are algebras for a functor and thus the free algebras can be obtained by a direct limit process. Dually, the final coalgebras can be obtained by an inverse limit process.

Free Pre-Lie Algebras are Free as Lie Algebras [PDF]

open access: yesCanadian Mathematical Bulletin, 2010
AbstractWe prove that the -module PreLie is a free Lie algebra in the category of -modules and can therefore be written as the composition of the -module Lie with a new -module X. This implies that free pre-Lie algebras in the category of vector spaces, when considered as Lie algebras, are free on generators that can be described using X.

Free monadic algebras [PDF]

open access: yesProceedings of the American Mathematical Society, 1959
A monadic (Boolean) algebra is a Boolean algebra A together with an operator 3 on A (called an existential quantifier, or, simply, a quantifier) such that 30=0, pfk 3p, and 3(^A 3q) = 3p* 3g whenever p and q are in A. Most of this note uses nothing more profound about monadic algebras than the definition. The reader interested in the motivation for and

SATURATED FREE ALGEBRAS REVISITED [PDF]

open access: yesThe Bulletin of Symbolic Logic, 2015
AbstractWe give an exposition of results of Baldwin–Shelah [2] on saturated free algebras, at the level of generality of complete first order theoriesTwith a saturated modelMwhich is in the algebraic closure of an indiscernible set. We then make some new observations whenM isa saturated free algebra, analogous to (more difficult) results for the free ...

Novel Free Differential Algebras for Supergravity

open access: yesUniverse, 2023
We develop the theory of Free Integro-Differential Algebras (FIDA) extending the powerful technique of Free Differential Algebras constructed by D. Sullivan. We extend the analysis beyond the superforms to integral- and pseudo-forms used in supergeometry.
