Eigenvalue Problem: A mathematical formulation in which one seeks to find scalar values (eigenvalues) and corresponding functions (eigenfunctions) that satisfy a given operator equation under ...

New error estimates for eigenvalues of symmetric integral equations are obtained. These estimates are applicable to a more general class of integration methods and, in many cases, are better than ...

Spectral theory provides a rigorous framework for analysing the eigenvalues and eigenfunctions of differential operators that play an essential role in mathematical physics. In particular, Sturm ...

This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...
