Focusing on singular boundary eigenvalue problems, this reference delves into Fuchsian differential equations with multiple singularities, presenting innovative methods for discovering higher special functions. It emphasizes the role of singularities in shaping solution behaviors and introduces efficient techniques that yield previously unknown functional relationships. Historical context enriches the discussion, tracing theoretical developments through notable mathematicians, particularly highlighting George Cecil Jaffé's contributions to quantum mechanics and energy level calculations.
