This thematic series originates from the International Conference on Applied Mathematics and Analysis in Memory of Prof. Gusein Sh. Guseinov at Atilim University, Ankara, Turkey. Professor Gusein Sh. Guseinov (1951-2015) was a distinguished mathematician in several fields of research which include spectral theory, spectral geometry on Riemannian manifolds, linear and nonlinear analysis, direct and inverse spectral problems of difference and differential operators, and time scales. Professor Guseinov is recognized and respected throughout the mathematical world for his important contributions to the study of time scales and spectral theory of Sturm-Liouville operators. He published more than 100 scientific articles and has more than 2000 citations.
