A trace formula for the sturm-liouville type equation with retarded argument
(Ankara Üniversitesi, 2017)
In this paper, we deal with a discontinuous Sturm-Liouville problem with retarded argument and eigenparameter-dependent boundary conditions. We obtain the asymptotic formulas for the eigenvalues and the regularized trace ...
Some Korovkin type results via power series method in modular spaces
(Ankara University, 2016)
Abstract. In this paper, we obtain a Korovkin type approximation result for a sequence of positive linear operators deÖned on modular spaces with the use of power series method . We also provide an example which satisfies ...
Effect of N doping on TL2GA2S3SE single crystals: thermoluminescence characterization of defect centers
(Eskişehir Teknik Üniversitesi, 2018)
Thermoluminescence study on nitrogen doped Tl2Ga2S3Se single crystals was achieved by performing the experiments with different stopping temperatures of 10−24 K and various heating rates between 0.4 and 1.2 K/s below room ...
