The Titchmarsh-Weyl Eigenfunction Expansion Theorem for Sturm-Liouville Differential Equations, the endpoint . can be regular, limit-circle or limit-point; nevertheless it is shown that these conditions lead to the definition of a single Titchmarsh-Weyl .-coefficient. From this coefficient the complex function theory methods of Titchmarsh provide a guide to a new proof of the general eigenfun

,Sturm’s 1836 Oscillation Results Evolution of the Theory,s shown how they apply to scalar equations to give a natural extension of Sturm’s second-order case. Finally we return to the second-order case to show how the indexing of zeros of eigenfunctions changes when there is a parameter in the boundary condition or if the weight function changes sign.

Charles Sturm and the Development of Sturm-Liouville Theory in the Years 1900 to 1950,self-adjoint operators in the abstract theory of Hilbert spaces and in the theory of ordinary linear differential equations..In addition to giving some details of these varied contributions an attempt is made to show the interaction between these two different methods of studying Sturm-Liouville theory.
