Using the inequality, we study the dependence of the solution on the order and the initial condition of a fractional differential equation. Gronwall-bel,man-inequality solutions of this equation are given by the confluent hypergeometric functions CHFs. Firstly the initial value problem is transformed into a equivalent Volterra-type integral equation under appropriate assumptions. DOI: 10.1090/S0002-9939-1972-0298188-1 Corpus ID: 28686926. Gronwall’s inequality for systems of partial differential equations in two independent variables @inproceedings{Snow1972GronwallsIF, title={Gronwall’s inequality for systems of partial differential equations in two independent variables}, author={Donald R. Snow}, year={1972} } partial differential equation appears in the inequality. By using a representation of the Riemann function, the result is shown to coincide with an earlier result obtained by Walter using an entirely different approach.

For any positive integer n, let un(t) designate the solution of the equation. ˙u = ω(t, u) +.

Suppose there is a polynomial f with non-negative coefficients such that.

Walter [ 171 gave a more natural extension of the Gronwall-Bellman inequality in several variables by using the properties of monotone operators. Snow [ 151 obtained corresponding inequality in two- variable scalar- and vector-valued functions by using the notion of a Riemann function. Young [ 191 established Gronwall’s Some New Gronwall-bihari Type Inequalities and Its Application in the Analysis for Solutions to Fractional Differential Equations, K. Boukerrioua, D. Diabi, B. Kilani, In this paper, we derive some generalizations of certain Gronwall-Bihari with weakly singular kernels for functions in one variable, which provide explicit bounds on unknown functions.To show the feasibility of the obtained partial differential equation appears in the inequality.

The aim of the present paper is to establish some new integral inequalities of Gronwall type involving functions of two independent variables which provide explicit bounds on unknown functions. The inequalities given here can be used as tools in the qualitative theory of certain partial differential and integral equations.

Lemma 1.1 (classical di erential version of Gronwall lemma). We assume that u2C([0;T);R), T2(0;1), satis es the di erential inequality (1.1) u0 a(t)u+ b(t) on An inequality which interconnects the argument, the unknown function and its derivatives, e.g. $$\tag {1 } y ^ \prime ( x) > f ( x , y ( x) ) ,$$. where $y$ is an unknown function of the argument $x$. The principal problem in the theory of differential inequalities is to describe, starting from a known differential inequality and additional (initial or boundary) conditions, all its solutions.
