“…In the modelling of various processes in mathematics physics, biology, dynamical systems, control systems, engineering and so on 1,2,3,4,5,6,7,8 , fractional partial differential equations are utilized since the results of fractional mathematical models have better results than other mathematical models. Therefore quite a few research such as existence, uniqueness and regularity of solutions, on the processes of heat diffusion, modelled by fractional differential equations 9,10,11 .…”
