Capturing Multiple Singularities with Spectral Accuracy for Multi-Term Fractional Differential Equations

This paper develops a robust numerical scheme based on a frame collocation method for solving multi-term fractional ordinary differential equations (FODEs) whose solutions exhibit multiple singularities at the origin. To adaptively capture the singular behavior, we construct a hybrid basis-function...
