Splittings and Symbolic Powers of Square-free Monomial Ideals [PDF]
International mathematics research notices, 2018 We study the symbolic powers of square-free monomial ideals via symbolic Rees algebras and methods in prime characteristic. In particular, we prove that the symbolic Rees algebra and the symbolic associated graded algebra are split with respect to a ...

Construction of a non-standard quantum field theory through a generalized Heisenberg algebra [PDF]
, 2001 We construct a Heisenberg-like algebra for the one dimensional quantum free Klein-Gordon equation defined on the interval of the real line of length $L$.

Sums of squares in octonion algebras [PDF]
Proceedings of the American Mathematical Society, 2005 Sums of squares in composition algebras are investigated using methods from the theory of quadratic forms. For any integerm≥1m\geq 1octonion algebras of level2m2^mand of level2m+12^m+1are constructed.

Sine-square deformation and Möbius quantization of 2D conformal field theory [PDF]
, 2016 Motivated by sine-square deformation (SSD) for quantum critical systems in 1+1-dimension, we discuss a Mobius quantization approach to the two-dimensional conformal field theory (CFT), which bridges the conventional radial quantization and the dipolar ...

Compact coalgebras, compact quantum groups and the positive antipode [PDF]
, 2009 In this article -that has also the intention to survey some known results in the theory of compact quantum groups using methods different from the standard and with a strong algebraic flavor- we consider compact o-coalgebras and Hopf algebras.

Stringy symmetries and the higher spin square [PDF]
, 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 ...

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

On algebras of generalized Latin squares [PDF]
Mathematica Bohemica, 2011 The main result of this paper is the introduction of a notion of a generalized $R$-Latin square, which includes as a special case the standard Latin square, as well as the magic square, and also the double stochastic matrix. Further, the algebra of all generalized Latin squares over a commutative ring with identity is investigated.

Chiral algebras of two-dimensional SYK models
Journal 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 ...
