Rule or exception? Planetary nebulae around hot subdwarf stars
A. Aller, L. F. Miranda, A. Ulla +4
In this work, we present the first results of an ongoing survey to search for planetary nebulae (PNe) around hot subdwarf stars (sdOs). Deep images and intermediate-resolution long…
On the degenerations of solvable Leibniz algebras
J. M. Casas, A. Kh. Khudoyberdiyev, M. Ladra +1
The present paper is devoted to the description of rigid solvable Leibniz algebras. In particular, we prove that solvable Leibniz algebras under some conditions on the nilradical a…
A basic class of symmetric orthogonal polynomials of a discrete variable
Mohammad Masjed-Jamei, Iván Area
By using a generalization of Sturm-Liouville problems in discrete spaces, a basic class of symmetric orthogonal polynomials of a discrete variable with four free parameters, which…
Left-right Noncommutative Poisson algebras
José M. Casas, Tamar Datuashvili, Manuel Ladra
The notions of left-right noncommutative Poisson algebra ($\NP^{lr}$-algebra) and left-right algebra with bracket $\AWB^{lr}$ are introduced. These algebras are special cases of $\…
Towards accelerating Smoothed Particle Hydrodynamics simulations for free-surface flows on multi-GPU clusters
Daniel Valdez-Balderas, José M. Domínguez, Benedict D. Rogers +1
Starting from the single graphics processing unit (GPU) version of the Smoothed Particle Hydrodynamics (SPH) code DualSPHysics, a multi-GPU SPH program is developed for free-surfac…
Cohomology of algebras over weak Hopf algebras
J. N. Alonso Alvarez, J. M. Fernandez Vilaboa, R. Gonzalez Rodriguez
In this paper we present the Sweedler cohomology for a cocommutative weak Hopf algebra H. We show that the second cohomology group classifies completely the weak crossed products,…
