Abstract:

This paper employs the method of successive approximations to investigate the existence of solutions for a class of initial value problems of fractional $q$-difference equations, as well as the existence of solutions for their corresponding systems. Subsequently, it presents approximate solutions for two specific types of fractional $q$-difference initial value problems (the fractional $q$-difference pantograph equation and the fractional $q$-difference Ambartsumian equation) along with their associated systems. Special emphasis is placed on discussing and analyzing several key properties of the approximate solutions for these two special equations.

Key words: initial value problem, fractional $q$-differential, continuous approximation method, approximate solutions
