Critical point equation on almost f-cosymplectic manifolds [PDF]

Arab Journal of Mathematical Sciences, 2023
Purpose – Besse first conjectured that the solution of the critical point equation (CPE) must be Einstein. The CPE conjecture on some other types of Riemannian manifolds, for instance, odd-dimensional Riemannian manifolds has considered by many geometers.

Local Shape of the Vapor–Liquid Critical Point on the Thermodynamic Surface and the van der Waals Equation of State

Frontiers in Physics, 2021
Differential geometry is a powerful tool to analyze the vapor–liquid critical point on the surface of the thermodynamic equation of state. The existence of usual condition of the critical point (∂p/∂V)T=0 requires the isothermal process, but the ...

On a new critical point theorem and some applications to discrete equations [PDF]

Opuscula Mathematica, 2014
Using the Fenchel-Young duality we derive a new critical point theorem. We illustrate our results with solvability for certain discrete BVP. Multiple solutions are also considered.

Certain Paracontact Metrics Satisfying the Critical Point Equation

Communications in Mathematics, 2023
The aim of this paper is to study theCPE (Critical Point Equation) on some paracontact metric manifolds.First, we prove that if a para-Sasakian metric satisfies the CPE,then it is Einstein with constant scalar curvature -2n(2n+1). Next,we prove that if $(\kappa,\mu)$-paracontact metric satisfies theCPE, then it is locally isometric to the product of a ...

Effective Rheology of Bi-viscous Non-newtonian Fluids in Porous Media

Frontiers in Physics, 2020
We model the flow of bi-viscous non-Newtonian fluids in porous media by a square lattice where the links obey a piece-wise linear constitutive equation.

Off-of-equilibrium effects on Kurtosis Along Strangeness-Neutral Trajectories [PDF]

EPJ Web of Conferences, 2022
The Beam Energy Scan program at the Relativistic Heavy Ion Collider (RHIC) is searching for the QCD critical point. The main signal for the critical point is the kurtosis of the distribution of proton yields obtained on an event by event basis where one ...

Mapping the critical equation of state by resummations [PDF]

EPJ Web of Conferences
Determining the existence and the location of the QCD critical point remains a major goal in the heavy-ion collision experiments. A crucial theoretical input for achieving this goal is mapping the QCD equation of state in the presence of baryon chemical ...
