“…The SLEs, which were investigated a long time ago, have many applications in various areas of science, engineering, and mathematics [34,53]. However, its fractional formulation and numerical methods for the solutions have started very recently [18,19,21,22,33,43,48,51,52]. The classical Sturm-Liouville problem (SLP ) for a linear second order differential equation is a boundary value problem (BV P ) of the form:…”
