Half Inverse Problem for the Impulsive Diffusion Operator with Discontinuous Coefficient
Cakmak, Yasar; Isik, Seval (UNIV NIS, FAC SCI MATH, 2016)The half inverse problem is to construct coefficients of the operator in a whole interval by using one spectrum and potential known in a semi interval. In this paper, by using the Hocstadt-Lieberman and Yang-Zettl's methods ... -
Recovery of the Impulsive Diffusion Operator with Discontinuous Coefficient
Cakmak, Yasar; Isik, Seval (NATURAL SCIENCES PUBLISHING CORP-NSP, 2014)In this work impulsive diffusion operator with discontinuous coefficient is considered. Integral representation is derived and some important properties of eigenvalues are studied. Moreover, it is proven that the coefficients ... -
A study of stability and bifurcation analysis in discrete-time predator-prey system involving the Allee effect
Isik, Seval (WORLD SCIENTIFIC PUBL CO PTE LTD, 2019)This paper deals with a discrete-time predator-prey system which is subject to an Allee effect on prey. We investigate the existence and uniqueness and find parametric conditions for local asymptotic stability of fixed ...
