Separated representations and algorithms for multidimensional operators

Separated representation of multidimensional integral operators with radially symmetric kernels leads to fast algorithms for their application. This approach is also applicable to singular and hypersingular operators ubiquitous in physics. Such approximations and algorithms are already used in quantum chemistry and have a strong potential to address computational problems in other applications. The talk is an overview of the approach and some of its applications.
