Eigenvalue problems in Riemannian geometry lie at the intersection of analysis, topology and global geometry. At their core is the study of spectral data—eigenvalues and eigenfunctions—associated with ...

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 ...

Numerical simulations in physics often require estimating a multitude of parameters, making the process computationally expensive and complex. Researchers at University of Tsukuba have introduced a ...
