Limit-point criteria for q-Sturm-Liouville equations

Bilender P. Allahverdiev, Huseyin Tuna

Abstract


In this article, the deficiency index problem of a singular q-Sturm Liouville problem is studied. We establish some criteria under which the q-Sturm Liouville equation is of limit-point case at infinity. 

Key words: q-Sturm-Liouville operator, limit-point case, indices defect.
