Nonlinear eigenvalue problems arise when one seeks pairs (λ,u) satisfying an equation of the form F(λ,u)=0 in a function space, subject to boundary or decay conditions. In contrast to linear spectral ...

Is it possible to deduce the shape of a drum from the sounds it makes? This is the kind of question that Iosif Polterovich, a professor in the Department of Mathematics and Statistics at Université de ...

Many quantum algorithms are developed to evaluate eigenvalues for Hermitian matrices. However, few practical approach exists for the eigenanalysis of non-Hermintian ones, such as arising from modern ...
