We are pleased to announce that the article titled "Minimality Properties of Sturm-Liouville Problems with Increasing Affine Boundary Conditions" authored by Yagub Aliyev, Assistant Professor in Mathematics and Statistics was published as a book chapter in the "Operator Theory, Functional Analysis and Applications".
"We consider Sturm-Liouville problems with a boundary condition linearly dependent on the eigenparameter. We concentrate the study on the cases where non-real or non-simple (multiple) eigenvalues are possible. We prove that the system of root (i.e. eigen and associated) functions of the corresponding operator, with an arbitrary function removed, form a minimal system in L2(0, 1), except some cases where this system is neither complete nor minimal.”
