“…For a comparative review and analysis of all definitions of FDs and fractional operators, we refer to Teodoro et al 15 From this newly defined derivative, many essential elements of the mathematical analysis of functions of a real variable have been successfully developed, among which we can mention: mean value theorem, Rolle's theorem, chain rule, conformable integration by parts formulas, conformable power series expansion, CDs, and integrals of complex-valued functions of a real variable, conformable boundary value problems: Sturm's theorems and Green's function, complex conformable integral (ComI), and conformable single and double Laplace transform (DLTr) definitions. 9,11,[16][17][18][19][20][21] The conformable partial derivative of the order γ ∈ (0, 1] of the real-valued functions of several variables and conformable gradient vector are defined, and a conformable Clairaut's theorem for partial derivatives is proven in Atangana et al 22 In Gözütok, 23 the conformable Jacobian matrix is introduced; chain rule for multivariable CD is defined; and the relation between conformable Jacobian matrix and conformable partial derivatives is investigated. In Martínez et al, 24 two new results on homogeneous functions involving their conformable partial derivatives are introduced, specifically the homogeneity of the conformable partial derivatives of a homogeneous function and conformable Euler's theorem.…”
