Picard’s Existence and Uniqueness Theorem Denise Gutermuth These notes on the proof of Picard’s Theorem follow the text Fundamentals of Di↵erential Equations and Boundary Value Problems, 3rd edition, by Nagle, Sa↵, and Snider, Chapter 13, Sections 1 and 2. The intent is to make it easier to understand the proof by supplementing

Charles Picard If an initial position of the vector x(t) is known, we get an initial value problem: dx dt = f(t, x), x(t0) = x0, where x0 is an initial column vector. Many brilliant mathematicians participated in proving the existence of a solution to the given initial value problem more than 100 years ago.

For a concrete example, I’ll show you how to solve problem #3 from section 2−8. Use the method of picard iteration with an initial guess y0(t) = 0 to solve: y′ = 2(y +1), y(0) = 0. Note that the initial condition is at the origin, so we just apply the iteration to this differential equation. y1(t) = Z t s=0 f(s,y0(s)) ds = Z t s=0 2(y0(s) +1) ds = Z t s=0

Theorem (Picard-Lindel¨of). Suppose f satisfies conditions (i) and (ii) above. Then for some c>0, the initial value problem (1) has a unique solution y= y(t) for |t−t0| <c. We will prove the Picard-Lindel¨of Theorem by showing that the sequence Y n(t) defined by Picard iteration is a Cauchy sequence of functions. Set M= Max(t,y)∈R|f(t,y ...

Moreover, the Picard iteration defined by yn+1(x)=y 0 + Zx x0 f(t,yn(t))dt produces a sequence of functions {yn(x)} that converges to this solution uniformly on I. Example 1: Consider the IVP y0 =3y2/3,y(2) = 0 Then f(x,y)=3y2/3 and @f @y =2y1/3,sof(x,y) is continuous when y = 0 but @f @y is not. Hence the hypothesis of Picard’s Theorem does not hold.
