“…With the continuous research on fractional differential equations by researchers, fractional differential equations have been developed rapidly in recent decades, and many scientific research achievements have also been made [1,3,8]. In recent years, some scholars have introduced the ideas and methods of fractional differential equations into the study of fractional q-difference equations, and also made some research achievements [2,4,5,6,9,10]. However, the definition of fractional order q-difference equation is more complex, so it is difficult to judge the solution of boundary value problems, especially in the study of the properties of Green function.…”
