Perfect fluid spacetimes with harmonic generalized curvature tensor [PDF]
, 2019 We show that n-dimensional perfect fluid spacetimes with divergence-free conformal curva- ture tensor and constant scalar curvature are generalized Robertson Walker (GRW) spacetimes; as a consequence a perfect fluid Yang pure space is a GRW spacetime. We

On Games of Perfect Information: Equilibria, epsilon-Equilibria and Approximation by Simple Games [PDF]
We show that every bounded, continuous at infinity game of perfect information has an epsilon-perfect equilibrium. Our method consists of approximating the payoff function of each player by a sequence of simple functions, and to consider the ...

Perfect-fluid, generalized Robertson-Walker space-times, and Gray’s decomposition [PDF]
, 2019 We give new necessary and sufficient conditions on the Weyl tensor for generalized Robertson-Walker (GRW) space-times to be perfect-fluid space-times.

Rainich-type Conditions for Perfect Fluid Spacetimes [PDF]
, 2014 In this worksheet we describe and illustrate a relatively simple set of new Rainich-type conditions on an n-dimensional spacetime which are necessary and sufficient for it to define a perfect fluid solution of the Einstein field equations. Procedures are

Advanced Materials, EarlyView.A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...

Perfect Fluid Spacetimes Admitting Almost Riemann Solitons
AxiomsIn this investigation, we examine the geometric character of almost Riemann solitons and gradient almost Riemann solitons in the context of perfect fluid solutions of the Einstein equations that admit a torse-forming vector field ζ.
