for continuous and locally integrable. Then, we have that, for. Proof: This is an exercise in ordinary differential Using Gronwall’s inequality, show that the solution emerging from any point $x_0\in\mathbb{R}^N$ exists for any finite time. Here is my proposed solution. We can first write $f(x)$ as an integral equation, $$x(t) = x_0 + \int_{t_0}^{t} f(x(s)) ds$$ where the integration constant is chosen such that $x(t_0)=x_0$. WLOG, assume that $t_0=0$. Then, The general form follows by applying the differential form to η ( t ) = K + ∫ t 0 t ψ ( s ) ϕ ( s ) d s {\displaystyle \eta (t)=K+\int _{t_{0}}^{t}\psi (s)\phi (s)\,\mathrm {d} s} which satisifies a differential inequality which follows from the hypothesis (we need ψ ( t ) ≥ 0 {\displaystyle \psi (t)\geq 0} for this; the first form is in fact not correct otherwise).

The differential form was proven by Grönwall in 1919. The integral form was Grönwall s inequality - Wikipedia.

Other variants and generalizations can be found in Pachpatte, B.G. (1998).[3] Differential form Proof We now show how to derive the usual Gronwall inequality from the abstract Gronwall inequality. For v : [0,T] → [0,∞) deﬁne Γ(v) by Γ(v)(t) = K + Z t 0 κ(s)v(s)ds. (2) 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].

In order to use Leray-Schauder theorem to show the existence of periodic solutions, we need a new generalized Gronwall inequality with impulse, mixed-type integral operator, andB-norm which is much diﬀerent from classical Gronwall inequality and can be used in other problemssuch as discussion on integrodiﬀerential equation of mixed type, see15. 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. Some generalizations of the Gronwall–Bellman (G–B) inequality are presented in this paper in continuous form and on time scales.

1,b Hence through the differential form Gronwell inequality, we obtain . 0 0 () [ ( ) ( ) ] 0 t t s ds t t yt e yt s ds The proof is trivial with integral form Gronwell inequality. Download Citation | A stochastic Gronwall inequality and its applications | In this paper, we show a Gronwall type inequality for Itô integrals (Theorems 1.1 and 1.2) and give some applications.

We are concerned here with some discrete generalizations of the following result of GronwaU [1], which has been very useful in the study of ordinary differential equations: Lemma (Gronwall). Some generalizations of the Gronwall–Bellman (G–B) inequality are presented in this paper in continuous form and on time scales.
