Discontinuous dependence of the ,-th Sturm-Liouville eigenvalueThe .-th eigenvalue of a regular Sturm-Liouville problem is not a continuous function of the boundary conditions. On the other hand if the index . is allowed to “jump”, then each eigenvalue can be embedded in an eigenvalue “branch” which is not only continuous but differentiable.

Note on Wirtinger’s inequalityIn this note we refine the following theorem due to W. Wirtinger: If . has period 2π and satisfies ., then . with strict inequality unless .(.) = . cos(.) + . sin(.), (., . ∈ ℝ).

Opial-type inequalities involving higher order partial derivatives of two functionsIn this paper we offer very general Opial-type inequalities involving higher order partial derivatives of two functions of two independent variables. From these inequalities we then deduce extended and improved versions of several recent results.

Inequalities for the first eigenvalues of the clamped plate and buckling problemse was finally proved by Nadirashvili in 1992, with important earlier contributions due to Szegő and Talenti. An analogous conjecture concerning the critical buckling load of a clamped plate was made by Pólya and Szegő around 1950. This conjecture remains open. This paper surveys the state of our kno
