On the Non-Abelian U-Duality of 11D Backgrounds

open access: yesUniverse, 2022
In this work, we generalise the procedure of the non-abelian T-duality based on a B-shift and a sequence of formal abelian T-dualities in non-isometric directions to 11-dimensional backgrounds.

On Instruction Sets for Boolean Registers in Program Algebra [PDF]

open access: yesScientific Annals of Computer Science, 2016
In previous work carried out in the setting of program algebra, including work in the area of instruction sequence size complexity, we chose instruction sets for Boolean registers that contain only instructions of a few of the possible kinds.

On the classification of nonsimple graph C*-algebras [PDF]

open access: yes, 2009
We prove that a graph C*-algebra with exactly one proper nontrivial ideal is classified up to stable isomorphism by its associated six-term exact sequence in K-theory.

Some Double Sequence Spaces of Fuzzy Real Numbers of Paranormed Type

open access: yesJournal of Mathematics, 2013
We study different properties of convergent, null, and bounded double sequence spaces of fuzzy real numbers like completeness, solidness, sequence algebra, symmetricity, convergence-free, and so forth. We prove some inclusion results too.

Spontaneous symmetry breaking from anyon condensation

open access: yesJournal of High Energy Physics, 2019
In a physical system undergoing a continuous quantum phase transition, spontaneous symmetry breaking occurs when certain symmetries of the Hamiltonian fail to be preserved in the ground state.

s-Sequences and Monomial Modules

open access: yesMathematics, 2021
In this paper we study a monomial module M generated by an s-sequence and the main algebraic and homological invariants of the symmetric algebra of M. We show that the first syzygy module of a finitely generated module M, over any commutative Noetherian ...

The Study of Neutrosophic Algebraic Structures and its Application in Medical Science [PDF]

open access: yesNeutrosophic Sets and Systems
Neutrosophic exact sequence and its construction is presented as algebraic structure in this article. A mathematical construction known as a neutrosophic exact sequence expands the implications of an exact sequence from classical algebra to the domain of

Vacuum String Field Theory ancestors of the GMS solitons [PDF]

open access: yes, 2002
We define a sequence of VSFT D-branes whose low energy limit leads exactly to a corresponding sequence of GMS solitons. The D-branes are defined by acting on a fixed VSFT lump with operators defined by means of Laguerre polynomials whose argument is ...

On Lacunary p-Absolutely Summable Fuzzy Real-Valued Double Sequence Space

open access: yesDemonstratio Mathematica, 2014
In this article, we introduce the class of p-absolutely summable fuzzy real valued double sequence (2lp)Fθ We have studied some algebraic properties like solid, symmetric, convergence free, sequence algebra.
