The University of Melbourne Recommended for you Under study is the integral inequality that has as kernel a nonnegative polynomial in the powers of the difference of arguments and a large parameter N. We establish some inequality whose form agrees with the celebrated Gronwall-Bellman inequality in which the argument of the exponent depends linearly on N. In this paper, some nonlinear Gronwall–Bellman type inequalities are established. Then, the obtained results are applied to study the Hyers–Ulam stability of a fractional differential equation and the boundedness of solutions to an integral equation, respectively. 2013-04-19 · If you have a disability and are having trouble accessing information on this website or need materials in an alternate format, contact web-accessibility@cornell.edu for assistance. 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. Perhaps, if we can quote a good reference, we can drop these assumptions.

THE GRONWALL INEQUALITY FOR MODIFIED STIELTJES INTEGRALS1 WAYNE W. SCHMAEDEKE AND GEORGE R. SELL 1. Introduction. It is well known [l ] that if u and v are nonnegative integrable functions and e>0 and if (1) u(t) :g e + f u(s)v(s)ds, (0 g * g T), J o then (2) u(t) ^Ke, (O^t^T), where 7C = exp f0v(s)ds.

2011-09-02 · In the past few years, the research of Gronwall-Bellman-type finite difference inequalities has been payed much attention by many authors, which play an important role in the study of qualitative as well as quantitative properties of solutions of difference equations, such as boundedness, stability, existence, uniqueness, continuous dependence and so on. Various linear generalizations of this inequality have been given; see, for example, [2, p. 37], [3], and [4].

In mathematics, Grönwall's inequality (also called Grönwall's lemma or the Grönwall–Bellman inequality) allows one to bound a function that is known to satisfy a certain differential or integral inequality by the solution of the corresponding differential or integral equation. The abstract Gronwall inequality applies much as before so to prove (4) we show that the solution of v(t) = K(t)+ Z t 0 κ(s)v(s)ds (5) is v(t) = K(t)+ Z t 0 K(s)κ(s))exp Z t s κ(r)dr ds (6) Equation (5) implies ˙v = K˙ + κv.

### In this notation, the hypothesis of Gronwall’s inequality is u ≤ Γ(u) where v ≤ w means v(t) ≤ w(t) for all t ∈ [0,T]. Since κ(t) ≥ 0 we have v ≤ w =⇒ Γ(v) ≤ Γ(w). Hence iterating the hypothesis of Gronwall’s inequality gives u ≤ Γn(u). Now change the dummy variable in (2) from s to s 1 and apply the inequality u(s 1) ≤ Γ(u)(s 1) to obtain Γ2(u)(t) = K + Z t 0 κ(s 1)K ds 1 + Z t 0 Z s 1 0 κ(s 1)κ(s 2)u(s 2)ds 2 ds 1
