Multiparameter -semigroups and multiparameter -cosine functions
Marko Kostic, Halis Can Koyuncuoglu, Youssef N. Raffoul
In this paper, we present several new results concerning multiparameter -semigroups. We introduce and systematically analyze the class of multiparameter -cosine functions, pr…
Existence of periodic solutions in shifts for neutral nonlinear dynamic systems
Murat Adivar, H. Can Koyuncuoglu, Youssef N. Raffoul
In this study, we focus on the existence of a periodic solution for the neutral nonlinear dynamic systems with delay% \[ x^Δ(t)=A(t)x(t)+Q^Δ\left(t,x\left(δ_{-}(s,t)\right) \right)…
Floquet theory based on new periodicity concept for hybrid systems involving -difference equations
Murat Adivar, H. Can Koyuncuoğlu
Using the new periodicity concept based on shifts, we construct a unified Floquet theory for homogeneous and nonhomogeneous hybrid periodic systems on domains having continuous, di…
Periodic and Asymptotically Periodic Solutions of Systems of Nonlinear Difference Equations with Infinite Delay
Murat Adıvar, H. Can Koyuncuoğlu, Youssef N. Raffoul
In this work we study the existence of periodic and asymptotically periodic solutions of a system of nonlinear Volterra difference equations with infinite delay. By means of fixed…
