“…Along these lines, all models viewed regarding FDE that may be existence of solutions, continuous dependence and parameters are also available in the concept of FDI-considering the fact that FDI occur in the mathematical modelling of specific models in financial aspects, optimal control, etc. and are usually investigated by numerous writers (see, for instance, [22][23][24] and the references therein). Fractional equation with delay properties arise in several fields such as biological and physical with state-dependent delay (SDD) or non-constant delay.…”
