A joint article by Khazar University's founder, Chairman of the Board of Directors and Trustees, Mathematics Department professor, and academician Hamlet Isakhanli, and Mathematics Department professor Bilander Allahverdiyev, titled "Eigenfunction expansions of impulsive dynamic Sturm-Liouville problems" has been published in the "Sahand Communications in Mathematical Analysis" journal (2024, Volume 21, No. 4). It is worth noting that the "Sahand Communications in Mathematical Analysis" journal is indexed in the "Web of Science" and "Scopus" databases.
This paper studies impulsive dynamic Sturm-Liouville boundary value problems. The existence of a countably infinite set of eigenvalues and eigenfunctions is proved and a uniformly convergent expansion formula in the eigenfunctions is established.
