Sturm-Liouville hypergroups without the compactness axiom

Rúben Sousa, Manuel Guerra, Semyon Yakubovich

We establish a positive product formula for the solutions of the Sturm-Liouville equation ℓ(u)=λu, where ℓ belongs to a general class which includes singular and degene…

The hyperbolic maximum principle approach to the construction of generalized convolutions

Rúben Sousa, Manuel Guerra, Semyon Yakubovich

We introduce a unified framework for the construction of convolutions and product formulas associated with a general class of regular and singular Sturm-Liouville boundary value pr…
