Blaschke inductive limits of uniform algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
We consider and study Blaschke inductive limit algebrasA(b), defined as inductive limits of disc algebras A(D) linked by a sequence b={Bk}k=1∞ of finite Blaschke products.

Hierarchical Zonotopal Power Ideals [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
Zonotopal algebra deals with ideals and vector spaces of polynomials that are related to several combinatorial and geometric structures defined by a finite sequence of vectors.

On the symmetric algebra of syzygy modules of monomial ideals

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2014
We consider the symmetric algebra of the first syzygy module of a monomial ideal generated by an s-sequence. We introduce on that algebra an admissible term order which allows us to compute its algebraic invariants.

On the class of p-absolutely summable sequence ( ) i  p of interval numbers [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2016
In this article we have studied on the class of p-absolutely summable sequence of interval numbers. We have discussed some important properties like linearity, completeness, solidity, symmetry and inclusion relation.

On Gelfand-Mazur theorem on a class of F-algebras

open access: yesTopological Algebra and its Applications, 2014
A topological algebra A is said to be fundamental if there exists b > 1 such that for every sequence(xn) in A, (xn) is Cauchy whenever the sequence bn(xn − xn-1) tends to zero as n → ∞.

The T-algebra spectral sequence: Comparisons and applications [PDF]

open access: yes, 2014
In previous work with Niles Johnson the author constructed a spectral sequence for computing homotopy groups of spaces of maps between structured objects such as G-spaces and E_n-ring spectra.

Quantum exchangeable sequences of algebras [PDF]

open access: yesIndiana University Mathematics Journal, 2009
We extend the notion of quantum exchangeability, introduced by K stler and Speicher in arXiv:0807.0677, to sequences ( _1, _2,...c) of homomorphisms from an algebra C into a noncommutative probability space (A, ), and prove a free de Finetti theorem: an infinite quantum exchangeable sequence ( _1, _2,...c) is freely independent and identically ...

p-Absolutely summable sequences of fuzzy real numbers [PDF]

open access: yesMaejo International Journal of Science and Technology, 2013
In this paper the fuzzy sequence space is introduced and some algebraic properties such as solidness, symmetricalness, convergence free and sequence algebra are studied, and some inclusion relations for the space are provided.

The Hochschild cohomology ring of the singular cochain algebra of a space [PDF]

open access: yes, 2011
We determine the algebra structure of the Hochschild cohomology of the singular cochain algebra with coefficients in a field on a space whose cohomology is a polynomial algebra.

Gysin sequences and SU(2)‐symmetries of C∗‐algebras

open access: yesTransactions of the London Mathematical Society, 2021
Motivated by the study of symmetries of C∗‐algebras, as well as by multivariate operator theory, we introduce the notion of an SU(2)‐equivariant subproduct system of Hilbert spaces. We analyse the resulting Toeplitz and Cuntz–Pimsner algebras and provide
