1973] THE SOLUTION OF A NONLINEAR GRONWALL INEQUALITY 339 Lemma 9 is a special case of Theorem 5.6 [1, p. 315]. Lemma 10. If G is a function from RxRtoR such that (b G exists, then G e OA° on [a, b] [1, Theorem 4.1]. Theorem 1. Given, c e R and c > 0 ; …
The Gronwall inequality as given here estimates the di erence of solutions to two di erential equations y0(t)=f(t;y(t)) and z0(t)=g(t;z(t)) in terms of the di erence between the initial conditions for the equations and the di erence between f and g. The usual version of the inequality is when

HOLTE Variations of Gronwall’s Lemma Gronwall’s lemma, which solves a certain kind of inequality for a function, is useful in the theory of differential equations. Here is one version of it [1, p, 283]: 0. Gronwall’s inequality.
Gronwall’s Inequality JWR January 10, 2006 Our purpose is to derive the usual Gronwall Inequality from the following Abstract Gronwall Inequality Let M be a topological space which also has a partial order which is sequentially closed in M × M. Suppose that a map Γ : M → M preserves the order relation and has an attractive fixed point v The original inequality seems to have rst appeared in 1919 in a paper [1] of Gronwall. These notes are based on a lecture and some homework problems given in a graduate class in ordinary di erential equations in the spring of 1997. 2. The Inequality Theorem 2.1 (The Gronwall Inequality). Let X be a Banach space and U ˆ X an open set in X.Letf A short and simple proof of an inequality of the Gronwall type is given for a class of integral systems based upon the generalized Gronwall lemma of Sansone-Conti. View Show abstract di⁄erentiable in y in order to be Lipschitz continuous.
5. Another discrete Gronwall lemma Here is another form of Gronwall’s lemma that is sometimes invoked in differential equa-tions [2, pp.
The Gronwall–Bellman inequality in the case of weighted function is also obtained. By the help of the new proposed inequalities, examples of Riemann–Liouville and Caputo proportional fractional initial value problems are presented to emphasize the solution dependence on the initial data and on …

Generalizations of the classical Gronwall inequality when the kernel of the associated integral equation is weakly singular are presented. The continuous and discrete versions are both given; the former is included since it suggests the latter by analogy.

Gronwall-Bellman inequalit y , which is usually proved in elementary di ff erent ial For example, Conlan and Diaz [ 71 generalized the Gronwall-Bellman inequality in n variables in order to prove uniqueness of solutions of a nonlinear partial differential equation. Walter [ 171 gave a more natural extension of the Gronwall-Bellman inequality in several variables by using the properties of Gronwall type inequalities of one variable for the real functions play a very important rule. The first use of the Gronwall inequality to establish boundedness and stability is due to R.Belman.
di⁄erentiable in y in order to be Lipschitz continuous. For example, f (x) = jxj is Lipschitz continous in x but f (x) = p x is not. Now we can use the Gronwall™s inequality to show that the solution of an initial value problem depends continuously on the initial data. Theorem Suppose, for positive constants and ; f (y;t) is Lipschitz con-

Any other proof for the Gronwall's inequality? 7. In this paper, some new Gronwall-type inequalities, which can be used as a handy tool in the qualitative and quantitative analysis of the solutions to certain fractional differential equations, are presented. The established results are extensions of some existing Gronwall-type inequalities in the literature. Based on the inequalities established, we investigate the boundedness, uniqueness For example, Ye and Gao considered the integral inequalities of Henry-Gronwall type and their applications to fractional differential equations with delay; Ma and Pečarić established some weakly singular integral inequalities of Gronwall-Bellman type and used them in the analysis of various problems in the theory of certain classes of differential equations, integral equations, and evolution Various linear generalizations of this inequality have been given; see, for example, [2, p. 37], [3], and [4]. In most of these cases, the upper bound for u is just the solution of the equation corresponding to the integral inequality of the type (1).
