Stringy symmetries and the higher spin square [PDF]

open access: yes, 2015
Tensionless string theory on AdS 3 × S 3 × T 4 ?> , as captured by a free symmetric product orbifold, has a large set of conserved currents which can be usefully organized in terms of representations of a  = ( 4 , 4 ) ?> supersymmetric higher spin ...

The Hopf algebra of diagonal rectangulations [PDF]

open access: yes, 2011
We define and study a combinatorial Hopf algebra dRec with basis elements indexed by diagonal rectangulations of a square. This Hopf algebra provides an intrinsic combinatorial realization of the Hopf algebra tBax of twisted Baxter permutations, which ...

On the algebra of symmetries of Laplace and Dirac operators [PDF]

open access: yes, 2017
We consider a generalization of the classical Laplace operator, which includes the Laplace–Dunkl operator defined in terms of the differential-difference operators associated with finite reflection groups called Dunkl operators.

Hilbert Modules - Square Roots of Positive Maps [PDF]

open access: yes, 2009
We reflect on the notions of positivity and square roots. We review many examples which underline our thesis that square roots of positive maps related to *-algebras are Hilbert modules.

Chiral algebras of two-dimensional SYK models

open access: yesJournal of High Energy Physics, 2019
We study chiral algebras in the Q ¯ $$ \overline{Q} $$ -cohomology of two dimensional SYK models with extended supersymmetry. In a special limit discovered in [1], we are able to construct explicitly a “vertical” single-particle higher-spin algebra that ...

An Algebra of Non-commutative Bounded Semimartingales: Square and Angle Quantum Brackets

open access: yes, 1994
Thanks to the extension of the non-commutative stochastic calculus on Fock space developed by Attal and Meyer, we give a ∗-algebra for the composition of non-commutative semimartingales.

ON SELBERG-TYPE SQUARE MATRICES INTEGRALS [PDF]

open access: yesJournal of Algebraic Systems, 2013
In this paper we consider Selberg-type square matrices integrals with focus on Kummer-beta types I & II integrals. For generality of the results for real normed division algebras, the generalized matrix variate Kummer-beta types I & II are defined under ...

Radial Toeplitz Operators on the Fock Space and Square-Root-Slowly Oscillating Sequences [PDF]

open access: yes, 2015
In this paper we show that the C*-algebra generated by radial Toeplitz operators with $$L_{\infty }$$L∞-symbols acting on the Fock space is isometrically isomorphic to the C*-algebra of bounded sequences uniformly continuous with respect to the square ...

PERMANENT AND DOMINANT OF MATRIX OVER INTERVAL MIN-PLUS ALGEBRA

open access: yesBarekeng
A min-plus algebra is a set , where is the set of all real numbers equipped with two binary operations, namely minimum and addition . Every square matrix in min-plus algebra can always be calculated as a permanent and dominant matrix.
