On the topology of geometric and rational orbits for algebraic group actions over valued fields

Journal of group theroy, 2020
In this note, we study the relationship between Zariski and relative closedness for actions of (smooth) algebraic groups defined over valued (mainly local) fields of any characteristic.

Local-global Galois theory of arithmetic function fields

Israel Journal of Mathematics, 2017
We study the relationship between the local and global Galois theory of function fields over a complete discretely valued field. We give necessary and sufficient conditions for local separable extensions to descend to global extensions, and for the local

Symmetry Analysis and Conserved Quantities for Lemaitre-Tolman-Bondi Spacetimes under f ( R ) Gravity

International Journal of Geometric Methods in Modern Physics (IJGMMP)
It is known that the Lemaitre-Tolman-Bondi (LTB) spacetimes describe spherically symmetric radially inhomogeneous models of the universe. Such models have widely been used to study gravitational collapse and late-time cosmic acceleration.

Algebraic length distribution of sequence duplications in whole genomes

2011 Seventh International Conference on Natural Computation, 2011
The field of comparative genomics relies upon inference of neutrality or selection from sequence conservation. Recent studies of exactly-conserved sequences have revealed an anomalous, algebraic distribution of conserved sequence lengths that is ...
