Numerical approaches to compute spectra of non-self adjoint operators in dimensions two and three
Fatima Aboud, François Jauberteau, Didier Robert
In this article we are interested for the numerical computation of spectra of non-self adjoint quadratic operators, in two and three spatial dimensions. Indeed, in the multidimensi…

Asymptotic expansion for nonlinear eigenvalue problems
Fatima Aboud, Didier Robert
In this paper we consider generalized eigenvalue problems for a family of operators with a quadratic dependence on a complex parameter. Our model is i…
