On approximate solutions for two higher-order Caputo-Fabrizio fractional integro-differential equations
(Springer International Publishing AG, 2017-08-03)We investigate the existence of solutions for two high-order fractional differential equations including the Caputo-Fabrizio derivative. In this way, we introduce some new tools for obtaining solutions for the high-order ... -
On extensions, Lie-Poisson systems, and dissipation
(Heldermann Verlag, 2022-07-06)Lie-Poisson systems on the dual spaces of unified products are studied. Having been equipped with a twisted 2-cocycle term, the extending structure framework allows not only to study the dynamics on 2-cocycle extensions, ... -
On head-on collision between two solitary waves in shallow water: the use of the extended PLK method
(Springer, 2015-10)In the present work, we examined the head-on collision of solitary waves in shallow water theory, through the use of extended Poincare–Lighthill–Kuo (PLK) method based on the combination of reductive perturbation method ... -
On progressive wave solution for non-planar KDV equation in a plasma with q-nonextensive electrons and two oppositely charged ions
(Işık University Press, 2020)In this paper, the ion-acoustic wave is investigated in a plasma with q-nonextensive electrons and two oppositely charged ions with varying masses. These parameters are found to modify the linear dispersion relation and ... -
On some nonlinear waves in fluid-filled viscoelastic tubes: Weakly dispersive case
(2005-06)By employing the nonlinear equations of motion of an incompressible, isotropic and prestressed thin viscoelastic tube and the approximate equations of an incompressible inviscid fluid, we studied the existence of some ... -

On the class of harmonic mappings which is related to the class of bounded boundary rotation
(Elsevier Science Inc, 2015-09-15)The class of bounded radius of rotation is generalization of the convex functions. The concept of functions bounded boundary rotation originated from Loewner (1917). But he did not use the present terminology. It was Paatero ... -
