Yang-Baxter deformations of the OSP(1|2) WZW model
Ali Eghbali, Yaghoub Samadi, Adel Rezaei-Aghdam
We obtain inequivalent classical r-matrices of the Lie superalgebra as real solutions of the graded (modified) classical Yang-Baxter equation, in such a way that the cor…
More on (gauged) WZW models over low-dimensional Lie supergroups and their integrable deformations
Ali Eghbali, Meysam Hosseinpour-Sadid, Adel Rezaei-Aghdam
In superdimension there are only three non-Abelian Lie superalgebras admitting non-degenerate ad-invariant supersymmetric metric, the well-known Lie superalgebra ,…
Geometric Dynamical Systems
Ghorbanali Haghighatdoost
This article provides a conceptual and historical review of the evolution of integrable Hamiltonian systems from the Moscow School of A. T. Fomenko to the emerging Azarbaijan Schoo…
Cosmological solutions in gravity via Noether symmetry approach
M. Mahmoudzadeh Baghbani, K. Atazadeh, M. Mousavi
Symmetry plays a crucial role in theoretical physics, especially Noether symmetry, which is a powerful approach for identifying the models at the fundamental level. The exact solut…
Energy conditions and gravitational baryogenesis in gravity
K. Atazadeh, S. Golsanamlou
In this work, first we examine the energy conditions in the context of the generalized metric-Palatini hybrid gravity, known as gravity. We show that for the propo…
Integrable deformed H WZW models and their non-Abelian duals as solutions of generalized supergravity equations
Ali Eghbali, Simin Ghasemi-Sorkhabi, Adel Rezaei-Aghdam
We show that the Yang-Baxter (YB) deformed backgrounds of the Wess-Zumino-Witten (WZW) model based on the Lie group can be considered as solutions of the generalized sup…
