On Sesquilinear Forms for Lower Semibounded (Singular) Sturm-Liouville Operators
Jussi Behrndt, Fritz Gesztesy, Seppo Hassi +2
Any self-adjoint extension of a (singular) Sturm-Liouville operator bounded from below uniquely leads to an associated sesquilinear form. This form is characterized in terms of pri…

Optimal Power-Weighted Birman--Hardy--Rellich-type Inequalities on Finite Intervals and Annuli
Fritz Gesztesy, Michael M. H. Pang
We derive an optimal power-weighted Hardy-type inequality in integral form on finite intervals and subsequently prove the analogous inequality in differential form. We note that th…
