Closed-form solutions to the conformable space-time fractional simplified MCH equation and time fractional Phi-4 equation

Results in Physics, 2020
The time-fractional problem is a class of important models to represent the real phenomena. We construct new solitary waves for the space-time fractional simplified modified Camassa-Holm (MCH) and the time fractional Phi-4 equations using the unified ...
