Some new soliton solutions for the nonlinear the fifth-order integrable equations

‎In this work‎, ‎we established some exact solutions for the‎ (۱+۱)-dimensional and (۲+۱)-dimensional fifth-order integrable‎ equations ((۱+۱)D and (۲+۱)D FOIEs) which is considered based on‎ the improved \tanh(\phi(\xi)/۲) expansion method (IThEM)‎, ‎by‎ utilizing Maple software‎. ‎We obtained new periodic solitary wave‎ ‎solutions‎. ‎The obtained solutions include soliton‎, ‎periodic‎, ‎kink‎, kink-singular wave solutions‎. ‎Comparing our new results with Wazwaz‎ results‎, ‎namely‎, ‎the Hereman-Nuseri method shows that our results give‎ further solutions‎. ‎Many other such types of nonlinear equations‎ arise in fluid dynamics‎, ‎plasma ‎physics,‎ and nonlinear physics‎.
