The analytic solutions of the LDEs are presented by utilizing a special kind of fractal function in a complex domain, linked with the subordination theory. The fractal functions are suggested for the multi-parametric coefficients type motorboat fractal set. We obtain different formulas of fractal analytic solutions of LDEs. Moreover, we determine the maximum value of the fractal coefficients to obtain the optimal solution. Through the subordination inequality, we determined the upper boundary determination of a class of fractal functions holding multibrot function v(z)=1+3 kappa z+z(3).eninfo:eu-repo/semantics/openAccessAnalytic FunctionSubordination And SuperordinationUnivalent FunctionOpen Unit DiskAlgebraic Differential EquationsComplex Fractal DomainFractional CalculusFractional Differential OperatorArticle5210.3390/fractalfract50200502-s2.0-85107851422WOS:000665178500001Q1Q1
