Braided Yangians

Dimitri Gurevich

Yangian-like algebras associated with current R-matrices different from the Yang ones are introduced. These algebras are of two types. The so-called braided Yangians are close to the Reflection Equation algebras, arising from involutive or Hecke symmetries. The Yangians of RTT type are close to the...

Radial solutions of the Dirichlet problem for a class of quasilinear elliptic equations arising in optometry

Chiara Corsato, Colette De Coster, Noemi Flora, Pierpaolo Omari

This paper deals with the quasilinear elliptic problem − div(∇u/\sqrt(1 + |∇u|^2))+ a(x)u = b(x)/\sqrt{1 + |∇u|^2} in B, u = 0 on ∂B, where B is an open ball in R^N, with N ≥ 2, and a, b ∈ C^1(B) are given radially symmetric functions, with a(x) ≥ 0 in B. This class of anisotropic prescribed mean...

About the gauge conditions arising in Finite Element magnetostatic problems

Emmanuel Creusé, Patrick Dular, Serge Nicaise

In this paper, we deal with some magnetostatic models considered in vector potential formulations and solved by a Finite Element solver. In order to ensure the uniqueness of the solution, a gauge condition has to be imposed, and several possibilities occur. Moreover, the source term has to be...

Two Guaranteed Equilibrated Error Estimators for Harmonic Formulations in Eddy Current Problems

Emmanuel Creusé, Yvonnick Le Menach, Serge Nicaise, Francis Piriou, Roberta Tittarelli

In this paper, two guaranteed equilibrated error estimators are proposed and compared for the 3D harmonic magnetodynamic problem of Maxwell's system. This system is recasted in the classical A − ϕ potential formulation or, equivalently , in the T − Ω potential formulation, and it is solved by...

Convergence analysis of a hp-finite element approximation of the time-harmonic Maxwell equations with impedance boundary conditions in domains with an analytic boundary

Serge Nicaise, Jérôme Tomezyk

We consider a non conforming hp-finite element approximation of a variational formulation of the time-harmonic Maxwell equations with impedance boundary conditions proposed in [5, §4.5.d]. The advantages of this formulation is that the variational space is embedded in H 1 as soon as the boundary is...
