Meet-reducible submaximal clones determined by nontrivial equivalence relations
Luc E. F. Diekouam, Etienne R. A. Temgoua, Marcel Tonga
The structure of the lattice of clones on a finite set has been proven to be very complex. To better understand the top of this lattice, it is important to provide a characterizati…
Reiterated homogenization of hyperbolic-parabolic equations in domains with tiny holes
Hermann Douanla, Erick Tetsadjio
This article studies the homogenization of hyperbolic-parabolic equations in porous media with tiny holes. We assume that the holes are periodically distributed and that the coeffi…
Weak decreasing stochastic order
Antoine-Marie Bogso, Patrice Takam Soh
We introduce the notion of weak decreasing stochastic (WDS) ordering for real-valued processes with negative means, which, to our knowledge, has not been studied before. Thanks to…
The emergence and analysis of Kuramoto-Sakaguchi-like models as an effective description for the dynamics of coupled Wien-bridge oscillators
L. Q. English, David Mertens, Saidou Abdoulkary +3
We derive the Kuramoto-Sakaguchi model from the basic circuit equations governing two coupled Wien-bridge oscillators. A Wien-bridge oscillator is a particular realization of a tun…
Linear partial divided-difference equation satisfied by multivariate orthogonal polynomials on quadratic lattices
D. D. Tcheutia, Y. Guemo Tefo, M. Foupouagnigni +2
In this paper, a fourth-order partial divided-difference equation on quadratic lattices with polynomial coefficients satisfied by bivariate Racah polynomials is presented. From thi…
Effects of critical fluctuations and dimensionality on the jump in specific heat at the superconducting transition temperature: Application to YBa2Cu_3 O_7 - δ, Bi_2 Sr_2CaCu_2 O_8+δand KOs_2 O_6 compounds
R. M. Keumo Tsiaze, A. V. Wirngo, S. E. Mkam Tchouobiap +3
We report on a study of the superconducting order parameter thermodynamic fluctuations in , $\mathrm{Bi}_{2}\mathrm{Sr}_{2}\mathrm{Ca…
