Inclusion graph of annihilators in a commutative ring
Hana Safari, Farzad Shaveisi, Reza Nikandish
Let be a commutative ring with identity, and let be the set of zero-divisors of . The inclusion graph of annihilators in , denoted by , is a graph w…
Supersymmetrization of deformed BMS algebras
Nabamita Banerjee, Arpita Mitra, Debangshu Mukherjee +1
and algebras are deformations of and algebra respectively. We present an supersymmetric…
Boundary Heisenberg Algebras and Their Deformations
Martin Enriquez-Rojo, H. R. Safari
We investigate the deformations and rigidity of boundary Heisenberg-like algebras. In particular, we focus on the Heisenberg and algebras w…
Flat space holography in spin-2 extended dilaton-gravity
Hamid Afshar, Erfan Esmaeili, Hamid Safari
We present an interacting spin-2 gauge theory coupled to the two-dimensional dilaton-gravity in flat spacetime. The asymptotic symmetry group is enhanced to the central extension o…
Deformation of Asymptotic Symmetry Algebras and Their Physical Realizations
H. R. Safari
This thesis is devoted to the study of the deformation and rigidity of infinite dimensional Lie algebras which are not subject to the Hochschild-Serre factorization theorem. In par…
Asymptotic Symmetries of Maxwell Chern-Simons Gravity with Torsion
H. Adami, P. Concha, E. Rodriguez +1
We present a three-dimensional Chern-Simons gravity based on a deformation of the Maxwell algebra. This symmetry allows introduction of a non-vanishing torsion to the Maxwell Chern…
On Stabilization of Maxwell-BMS Algebra
P. Concha, H. R. Safari
In this work we present different infinite dimensional algebras which appear as deformations of the asymptotic symmetry of the three-dimensional Chern-Simons gravity for the Maxwel…
BMS4 Algebra, Its Stability and Deformations
H. R. Safari, M. M. Sheikh-Jabbari
We continue analysis of \cite{Parsa:2018kys} and study rigidity and stability of the BMS4 algebra and its centrally extended version. We construct and classify the family of algebr…
On Rigidity of 3d Asymptotic Symmetry Algebras
A. Farahmand Parsa, H. R. Safari, M. M. Sheikh-Jabbari
We study rigidity and stability of infinite dimensional algebras which are not subject to the Hochschild-Serre factorization theorem. In particular, we consider algebras appearing…
