Partial *-algebras of Distributions

open access: yesPublications of the Research Institute for Mathematical Sciences, 2005
The problem of multiplying elements of the conjugate dual of certain kind of commutative generalized Hilbert algebras, which are dense in the set of C^∞ -vectors of a self-adjoint operator, is considered in the framework of the so-called duality ...

On the Existence Problem of Finite Bases of Identities in the Algebras of Recursive Functions

open access: yesМоделирование и анализ информационных систем, 2020
Raphael Robinson showed that all primitive recursive functions depending on one argument, and only they could be obtained from two functions s(x) = x +1 and q(x) = x - [√x]² by using operations of addition +, superposition ∗ and iteration i.

Pointers in Recursion: Exploring the Tropics [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
We translate the usual class of partial/primitive recursive functions to a pointer recursion framework, accessing actual input values via a pointer reading unit-cost function.

Partial Representations and Partial Group Algebras

open access: yesJournal of Algebra, 2000
The partial group algebra of a group G over a field K, denoted by K_{par}(G), is the algebra whose representations correspond to the partial representations of G over K-vector spaces. In this paper we study the structure of the partial group algebra K_{par}(G), where G is a finite group.

Bitraces on Partial O*-Algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2007
Unbounded bitraces on partial O*-algebras are considered, a class of ideals defined by them is exhibited, and several relationships between certain commutants, bicommutants, and tricommutants associated with the *-representations and ...

Real commutative division algebras [PDF]

open access: yes, 2007
The category of all two-dimensional real commutative division algebras is shown to split into two full subcategories. One of them is equivalent to the category of the natural action of the cyclic group of order 2 on the open right half plane ℝ>0 × ℝ ...

Which Arithmetical Data Types Admit Fracterm Flattening?

open access: yesScientific Annals of Computer Science, 2022
The formal theory of division in arithmetical algebras reconstructs fractions as syntactic objects called fracterms. Basic to calculation, is the simplification of fracterms to fracterms with one division operator, a process called fracterm ...

New Condition of Automatic Continuity of Dense Range Homomorphisms on Jordan – Banach Algebras [PDF]

open access: yesمجلة التربية والعلم, 2018
The following open problem stated that, if T: A⟶B is a dense range homomorphism between Banach algebras A and B such that B is semi-simple. Is T automatically continuous? (see [1]).
