Self-Similar Solutions and Global Existence for Nonlinear Reaction-Diffusion Systems in Industrial Ammonia Synthesis
Jamshid Khasanov, Sokhibjan Muminov, Sardor Jumaniyozov +2
This paper investigates a system of nonlinear reaction-diffusion equations modeling the industrial synthesis of ammonia. By applying Lie group analysis, we construct self-similar s…
Gravitational quasinormal modes of Dymnikova black holes
Bekir Can LütfüoÄlu, Erdinç UlaÅ Saka, Abubakir Shermatov +3
We investigate gravitational quasinormal modes of the Dymnikova black hole, a regular spacetime in which the central singularity is replaced by a de Sitter core. This geometry, ori…
Proper-Time Approach in Asymptotic Safety via Black Hole Quasinormal Modes and Grey-body Factors
Bekir Can LütfüoÄlu, Erdinç UlaÅ Saka, Abubakir Shermatov +3
We study the quasinormal mode spectrum and grey-body factors of black holes in an effectively quantum-corrected spacetime, focusing on the influence of near-horizon modifications o…
Dynamics of Interacting Murnaghan-Equation-of-State Fluids with Global Monopole and Nonlinear Power-Yang-Mills Hair in Critical-Dimension AdS Black Holes
Yassine Sekhmani, Sunil Kumar Maurya, Javlon Rayimbaev +4
We construct and analyze a novel family of exact higher-dimensional black hole solutions in Einstein-Power-Yang-Mills gravity minimally coupled to a scalar field multiplet supporti…
Cosmological implications and causality in gravity theory with observational constraints
Dinesh Chandra Maurya, Javlon Rayimbaev, Inomjon Ibragimov +1
In the generalized matter-geometry coupling theory, we investigate the physical characteristics and causality of some new cosmological models for a flat, homogeneous, and isotropic…
