Uniformly bounded Lebesgue constants for scaled cardinal interpolation with Matérn kernels
Aurelian Bejancu
For and positive integers , , such that , we study non-stationary interpolation at the points of the scaled grid via the Matérn kernel -…
Wiener-Hopf difference equations and semi-cardinal interpolation with integrable convolution kernels
Aurelian Bejancu
Let be a half-space lattice, defined either relative to a fixed coordinate (e.g.\ ), or relative to a linear orde…
On The splitting of the Einstein field equations with respect to a general threading of spacetime
Aurel Bejancu, Hani Reda Farran
Based on a general threading of the spacetime , we obtain a new and simple splitting of a both the Einstein field equations (EFE) and the conservation laws in $(M,g)…
Equations of Motion with Respect to the Threading of a Universe
Aurel Bejancu
We continue our research work started in "Kinematic Quantities and Raychaudhuri Equations in a Universe" (Eur. Phys. J. C, 2015), and obtain in a covariant form, the equations…
Kinematic Quantities and Raychaudhuri Equations in a Universe
Aurel Bejancu
Based on some ideas emerged from the classical Kaluza-Klein theory, we present a universe as a product bundle over the spacetime. This enables us to introduce and study t…
On the (1+3) threading of spacetime with respect to an arbitrary timelike vector field
Aurel Bejancu, Constantin Călin
We develop a new approach on the (1+3) threading of spacetime with respect to a congruence of curves defined by an arbitrary timelike vector field. The study is based on s…
