Exponentially convergent numerical-analytical method for solving eigenvalue problems for singular differential operators
Abstract
The article develops and proves an exponentially convergent numerical-analytical method (the FD-method) for solving Sturm-Liouville problems with a singular Legendre operator and a singular potential. Obtained within are sufficient conditions for convergence of the method and a priori estimates of its accuracy. A detailed algorithm for programmatic implementation of the FD-method is presented and compared with known algorithms (SLEIGN2).
