  • Solutions of Direct and Inverse Even-Order Sturm-Liouville Problems Using Magnus Expansion 
    Perera, U.; Böckmann, C. (Mathematics, 2019)
    In this paper Lie group method in combination with Magnus expansion is utilized to develop a universal method applicable to solving a Sturm–Liouville problem (SLP) of any order with arbitrary boundary conditions. It is ...
  • Solutions of Sturm-Liouville Problems 
    Perera, U.; Böckmann, C. (Mathematics, 2020)
    This paper further improves the Lie group method with Magnus expansion proposed in a previous paper by the authors, to solve some types of direct singular Sturm–Liouville problems. Next, a concrete implementation to the ...
