The oblate spheroidal wave functions (OSWF) are a special class of functions that arise in the solution of certain types of differential equations, particularly in problems involving wave propagation in systems that exhibit axial symmetry. They are closely related to the solutions of the spheroidal wave equation, which is a generalization of the well-known spherical wave equation.
