Numerical subspace algorithms for solving the tensor equations involving Einstein product

Numerical Linear Algebra with Applications, 2020
In this article, we propose some subspace methods such as the conjugate residual, generalized conjugate residual, biconjugate gradient, conjugate gradient squared and biconjugate gradient stabilized methods based on the tensor forms for solving the ...

Fourth-order tensor Riccati equations with the Einstein product

Linear and multilinear algebra, 2020
In this paper, the fourth-order tensor Riccati equation with the Einstein product is investigated. Using the Einstein product, we introduce the -tensor, the spectrum and the block tensor multiplication.

Thermal stress tensors in static Einstein Spaces

Physical Review D, 1982
The Bekenstein-Parker Gaussian path-integral approximation is used to evaluate the thermal propagator for a conformally invariant scalar field in an ultrastatic metric. If the ultrastatic metric is conformal to a static Einstein metric, the trace anomaly vanishes and the Gaussian approximation is especially good.

Zero Curvature Tensor in Einstein's Unified Field Theory

Physical Review, 1958
Im Gegensatz zur allgemeinen Relativitätstheorie, wo ein verschwindender Krümmungstensor für einen ebenen Raum charakteristisch ist, gilt dieser Sachverhalt nicht mehr in der Einsteinschen einheitlichen Feldtheorie. In der vorliegenden Arbeit wurden alle Lösungen abgeleitet und diskutiert, die einem verschwindenden Krümmungstensor in der Einsteinschen ...
