Backreaction in Numerical Relativity: Averaging on Newtonian gauge-like hypersurfaces in Einstein Toolkit cosmological simulations

The Open Journal of Astrophysics
We introduce a spatial averaging scheme and use it to study the evolution of spatial averages in large-scale simulations of cosmological structure formation performed with the Einstein Toolkit.

An eigenvalue estimate for self-shrinkers in a Ricci shrinker

Advanced Nonlinear Studies
In this paper, we study the drifted Laplacian Δf on a hypersurface M in a Ricci shrinker (M̄,g,f) $\left(\bar{M},g,f\right)$ . We prove that the spectrum of Δf is discrete for immersed hypersurfaces with bounded weighted mean curvature in a Ricci ...

On some almost contact metric hypersurfaces of W4-manifolds

Дифференциальная геометрия многообразий фигур, 2018
It is proved that 3-hypersurfaces of W4-manifolds admit an almost contact metric structures that can be identical to the structure induced on 2-hypersurfaces of such manifolds.

Evolution paths on the equilibrium manifold [PDF]

In a pure exchange smooth economy with fixed total resources, we de- fine the length between two regular equilibria belonging to the equilibrium manifold as the number of intersection points of the evolution path connecting them with the set of critical ...

Transformations for hypersurfaces with vanishing . . . [PDF]

, 2005
We provide a method of constructing families of hypersurfaces of a space form with zero Gauss-Kronecker curvature, from a given such hypersurface, based on Ribaucour transformations.

Canonical liftings of Calabi–Yau hypersurfaces: Dwork hypersurfaces

manuscripta mathematica
Abstract We explicitly compute canonical liftings modulo $$p^2$$ p 2 in a sense of Achinger–Zdanowicz of Dwork hypersurfaces.
