Numerical models of cosmological evolution of a degenerate Fermi-system of scalar charged particles [PDF]
Gravitation & Cosmology, 2014 Based on the previously constructed mathematical model of a statistical Fermi system with particle interaction, in this paper we construct and analyze numerical models of cosmological evolution of a single-component degenerate Fermi system of scalar ...

Phase-Space Analysis of an Einstein–Gauss–Bonnet Scalar Field Cosmology [PDF]
Mathematics, 2023 We perform a detailed study of the phase-space of the field equations of an Einstein–Gauss–Bonnet scalar field cosmology for a spatially flat Friedmann–Lemaître–Robertson–Walker spacetime.

Scalar Curvature, Entropy, and Generalized Ricci Flow [PDF]
International mathematics research notices, 2022 We derive a family of weighted scalar curvature monotonicity formulas for generalized Ricci flow, involving an auxiliary dilaton field evolving by a certain reaction–diffusion equation motivated by renormalization group flow.

Weak scalar curvature lower bounds along Ricci flow [PDF]
Science China Mathematics, 2021 In this paper, we study Ricci flow on compact manifolds with a continuous initial metric. It was known from Simon (2002) that the Ricci flow exists for a short time.

Future dynamics of FLRW for the massless-scalar field system with positive cosmological constant [PDF]
Journal of Mathematics and Physics, 2021 We consider solutions to the Einstein-massless-scalar field system with a positive cosmological constant, arising from sufficiently regular, near-FLRW (Friedmann-Lemaître-Robertson-Walker), initial data.
