Lagrangian submanifolds with constant angle functions of the nearly Kähler S3 × S3

Burcu Bektaş, Marilena Moruz, Joeri van Der Veken, Luc Vrancken

We study Lagrangian submanifolds of the nearly Kähler S3 × S3 with respect to their so called angle functions. We show that if all angle functions are constant, then the submanifold is either totally geodesic or has constant sectional curvature and there is a classification theorem that follows…

Improved Performance of Piezoelectric Transformer Mode Thickness by Nonlinear Methods

Aïda Chérif, Djamila Zehar, Khalissa Behih, Mohamed Rguiti

During these last years, the demand of miniaturized voltage transformers increased with the fast multiplication of portable equipment's. The miniaturization of the electromagnetic transformer is more difficult. An interesting solution consists of the use of the piezoelectric transformer of…

Blow–up for nonlinear Maxwell equations

Piero d'Ancona, Serge Nicaise, Roland Schnaubelt

We construct classical solutions to the nonlinear Maxwell system with periodic boundary conditions which blow up in H(curl). A similar result is shown on the full space. Our construction is based on an analysis of a shock wave in one space dimension.

Radiative heating of a glass plate: the semi-discrete problem

Luc Paquet

In a preceding paper (MSIA, 2012), we have studied the radiative heating of a glass plate. We have proved existence and uniqueness of the solution. Here, we want to study the semi-discrete problem and to prove a priori error estimates. Previously, in that purpose, we have to study the regularity of…

Comparison of Numerical Error Estimators for Eddy-Current Problems Solved by FEM

R. Tittarelli, Y. Le Menach, F. Piriou, Emmanuel Creusé, Serge Nicaise, J.-P. Ducreux

In the domain of field computation with the finite-element method, choosing the mesh refinement is an important step to obtain an accurate solution. In order to evaluate the quality of the mesh, a posteriori error estimators are frequently used. In this paper, we propose to analyze and to compare…

Flat almost complex surfaces in the nearly Kähler S3 × S3

Luc Vrancken

In this talk we show how to study almost complex submanifolds of S3 × S3. Compact 6-dimensional non-K¨ahler nearly K¨ahler manifolds do not admit 4-dimensional almost complex submanifolds, so the almost complex submanifolds are surfaces. Previously, a classification of the totally geodesic almost…

Flat Almost Complex Surfaces in the Homogeneous Nearly Kähler S3×S3

Bart Dioos, Haizhong Li, Hui Ma, Luc Vrancken

By employing a nice adapted frame we prove a Bonnet-type existence and uniqueness theorem for almost complex surfaces in the homogeneous nearly Kähler manifold S3×S3. The proof uses a local correspondence between almost complex surfaces in S3×S3 and surfaces in R3 that satisfy the Wente H-surface…
