Quiver Varieties, Category O for Rational Cherednik Algebras, and Hecke Algebras [PDF]

open access: yes, 2008
We relate the representations of the rational Cherednik algebras associated with the complex reflection group S-n x (mu e)(n) to sheaves on Nakajima quiver varieties associated with extended Dynkin graphs via a Z-algebra construction.

On RM-algebras with an additional condition [PDF]

open access: yesJournal of Mahani Mathematical Research
In this paper, we apply a new condition to RM-algebras. We obtain some relations among this condition with another axioms in some algebras of logic and some examples are given to illustrate them. %It is proved We prove that the relation derived from this

COMPUTABILITY IN PARTIAL COMBINATORY ALGEBRAS [PDF]

open access: yesThe Bulletin of Symbolic Logic, 2020
AbstractWe prove a number of elementary facts about computability in partial combinatory algebras (pca’s). We disprove a suggestion made by Kreisel about using Friedberg numberings to construct extensional pca’s. We then discuss separability and elements without total extensions.

IDENTITIES IN THE ALGEBRA OF PARTIAL MAPS [PDF]

open access: yesInternational Journal of Algebra and Computation, 2006
We consider the identities of a variety of semigroup-related algebras modelling the algebra of partial maps. We show that the identities are intimately related to a weak semigroup deductive system and we show that the equational theory is decidable. We do this by giving a term rewriting system for the variety.

Automorphisms of real Lie algebras of dimension five or less [PDF]

open access: yes, 2013
The Lie algebra version of the Krull-Schmidt Theorem is formulated and proved. This leads to a method for constructing the automorphisms of a direct sum of Lie algebras from the automorphisms of its indecomposable components.

Research on Partial Ordered Sets That Can Be Constructed as Effect Algebras

open access: yesDiscrete Dynamics in Nature and Society, 2022
In this paper, we study effect algebra-induced partial ordered sets. All possible cases of effect algebras generated by bounded partial ordered set MI of height 2 are given.

Unbounded C*-seminorms, biweights, and *-representations of partial *-algebras: A review

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
The notion of (unbounded) C*-seminorms plays a relevant role in the representation theory of *-algebras and partial *-algebras. A rather complete analysis of the case of *-algebras has given rise to a series of interesting concepts like that of ...

Weights on Partial *-Algebras

open access: yesJournal of Mathematical Analysis and Applications, 1995
Partial *-algebras were introduced by \textit{J.-P. Antoine} and \textit{W. Karwowski} [Publ. Res. Inst. Math. Sci. 21, 205-236 (1985; Zbl 0609.47058)] and studied by two of the authors with F. Mathot and A. Inoue in a sequence of papers. These algebras may include closable unbounded operators. In the present paper certain sesquilinear forms on partial

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 ...
