Representation of group isomorphisms. The compact case

María V. Ferrer, Margarita Gary, Salvador Hernández

Let be a discrete group and let and be two subgroups of -valued continuous functions defined on two -dimensional compact spaces and . A g…

A class of polynomial planar vector fields with polynomial first integral

A. Ferragut, C. Galindo, F. Monserrat

We give an algorithm for deciding whether a planar polynomial differential system has a first integral which factorizes as a product of defining polynomials of curves with only one…

Anisotropy of spin-orbit induced electron spin relaxation in [001] and [111] grown GaAs quantum dots

C. Segarra, J. Planelles, J. I. Climente +1

We report a systematic study of the spin relaxation anisotropy between single electron Zeeman sublevels in cuboidal GaAs quantum dots (QDs). The QDs are subject to an in-plane magn…

Simulations of Kinetic Electrostatic Electron Nonlinear (KEEN) Waves with Variable Velocity Resolution Grids and High-Order Time-Splitting

Bedros Afeyan, Fernando Casas, Nicolas Crouseilles +4

KEEN waves are nonlinear, non-stationary, self-organized asymptotic states in Vlasov plasmas outside the scope or purview of linear theory constructs such as electron plasma waves…

New Quantum Codes from Evaluation and Matrix-Product Codes

Carlos Galindo, Fernando Hernando, Diego Ruano

Stabilizer codes obtained via CSS code construction and Steane's enlargement of subfield-subcodes and matrix-product codes coming from generalized Reed-Muller, hyperbolic and affin…

Stanley depth and the lcm-lattice

Bogdan Ichim, Lukas Katthän, Julio José Moyano-Fernández

In this paper we show that the Stanley depth, as well as the usual depth, are essentially determined by the lcm-lattice. More precisely, we show that for quotients of monomia…
