Soliton Solutions of Klein–Fock–Gordon Equation Using Sardar Subequation Method

The Klein–Fock–Gordon equation (KFGE), defined as the of relativistic wave related to NLEEs, has numerous implications for energy particle physics and is useful a model several types matter, with deviation in basic stuffs particles crystals. In this work, Sardar subequation method (SSM) used finding solution KFGE. advantage SSM that it provides many different kinds solitons, such dark, bright, singular, periodic combined dark–singular dark–bright solitons. results show very reliable, simple can be functionalized other nonlinear equations. It verified all attained solutions are stable by modulation instability process. To enhance physical description solutions, some 3D, contour 2D graphs plotted taking precise values parameters using Maple 18.
