Anomalous diffusion has been detected in a wide variety of scenarios, from fractal media, systems with memory, transport processes in porous media, to fluctuations of financial markets, tumour growth, and of Gronwall’s Inequality EN HAO YANG Department of Mathematics, Jinan University, Gang Zhou, People’s Republic of China Submitted by J. L. Brenner Received May 13, 1986 This paper derives new discrete generalizations of the Gronwall-Bellman integral inequality. WangandFanJournalofInequalitiesandApplications20182018:336 Page3of10 Finally,letMp(0,T;Rd)(orMp simply)representthesetof(F t)-progressivelymeasurable Rd In this video, I state and prove Grönwall’s inequality, which is used for example to show that (under certain assumptions), ODEs have a unique solution. Basi analogues of Gronwall – Bellman inequality [3] or its variants. In recent years there have several linear and nonlinear discrete generalization of this useful inequality for instance see [1, 2, 4, 5].The aim of this paper is to establish some useful discrete inequalities which claim the following as their origin. Gronwall-Bellman inequality and its ﬁrst nonlinear generalization by Bihari (see Bellman and Cooke [1]), there are several other very useful Gronwall-like inequalities. Haraux [3, Corollary 16, page 139] derived one Gronwall-like in-equality and used it to prove the existence of solutions of wave equations with logarithmic nonlinearities.

### ii Preface As R. Bellman pointed out in 1953 in his book " Stability Theory of Differential Equations " , McGraw Hill, New York, the Gronwall type integral inequalities of one variable for real functions play a very important role in the Qualitative Theory of Differential Equations. The main aim of the present research monograph is to present some natural applications of Gronwall inequalities

We consider duality in these spaces and derive a Burkholder type inequality in a dual The method of proof does not rely on the use of the Kolmogorov equation or the Our Gronwall argument also yields weak error estimates which are uniform in time without any additional effort.

As an application, we accommodate the newly defined derivative to prove the uniqueness and obtain a bound in terms of Mittag-Leffler 1987-03-01 · Gronwall's inequality has undergone and continues to undergo substantial generalization [4], [2]. Our elementary proof of a discrete version of Gronwall's inequality concentrates on and improves the characterization of the multiplier ao in (3), (4), below.

CHAPTER 0 - ON THE GRONWALL LEMMA 3 2. Local in time estimates (from integral inequality) In many situations, it is not easy to deal with di erential inequalities and it is much more natural to start from the associated integral inequality. The conclusion can be however the same. Lemma 2.1 (integral version of Gronwall lemma).

### Gronwall™s Inequality We begin with the observation that y(t) solves the initial value problem dy dt = f(y(t);t) y(t 0) = y 0 if and only if y(t) also solves the integral equation y(t) = y 0 + Z t t 0 f (y(s);s)ds This observation is the basis for the following result which is known as Gron-wall™s inequality.
