Article Citation - WoS: 4An Introduction To Complex Functions on Products of Two Time Scales(Taylor & Francis Ltd, 2006) Bohner, Martin; Guseinov, Gusein SH.In this paper, we study the concept of analyticity for complex-valued functions of a complex time scale variable, derive a time scale counter-part of the classical Cauchy-Riemann equations, introduce complex line delta and nabla integrals along time scales curves, and obtain a time scale version of the classical Cauchy integral theorem.Article Citation - WoS: 52Citation - Scopus: 61Basics of Riemann Delta and Nabla Integration on Time Scales(Taylor & Francis Ltd, 2002) Guseinov, GS; Kaymakçalan, BIn this paper we introduce and investigate the concepts of Riemann's delta and nabla integrals on time scales. Main theorems of the integral calculus on time scales are proved.Article Citation - WoS: 1Citation - Scopus: 2Asymptotic Equivalence of Impulsive Dynamic Equations on Time Scales(Hacettepe Univ, Fac Sci, 2023) Akgol, Sibel DogruThe asymptotic equivalence of linear and quasilinear impulsive dynamic equations on time scales, as well as two types of linear equations, are proven under mild conditions. To establish the asymptotic equivalence of two impulsive dynamic equations a method has been developed that does not require restrictive conditions, such as the boundedness of the solutions. Not only the time scale extensions of former results have been obtained, but also improved for impulsive differential equations defined on the real line. Some illustrative examples are also provided, including an application to a generalized Duffing equation.Article Citation - WoS: 4Citation - Scopus: 4Existence of Positive Solutions of a Sturm-Liouville Bvp on an Unbounded Time Scale(Taylor & Francis Ltd, 2008) Topal, S. Gulsan; Yantir, Ahmet; Cetin, ErbilA fixed point theorem of Guo-Krasnoselskii type is used to establish existence results for the nonlinear Sturm-Liouville dynamic equation (p(t)x(Delta))(del) + lambda phi(t)f(t,x(t)) = 0 with the boundary conditions on an unbounded time scale. Later on the positivity and the boundedness of the solutions are obtained by imposing some conditions on f.
