Transformation Operator for Sturm-Liouville Operators with Growing Potentials

open access: yesAzerbaijan Journal of Mathematics
Summary: This paper considers a pair of Sturm-Liouville operators \(A=- \frac{d^2}{dx^2}+cx^{\alpha}\) and \(B=-\frac{d^2}{dx^2}+cx^{\alpha}+q(x)\) on the semi-axis \([0,\infty), c=const, \alpha \geq 1\). A transformation operator with a condition at infinity is constructed for the operators \(A\) and \(B\).
