Picard Iteration. Under certain conditions on f(to be discussed below), the solution of (2) is the limit of a Cauchy Sequence of functions: Y(t) = lim n→∞ Y n(t) where Y0(t) = y0 the constant function and Y n+1(t) = y0+ Z t t0 f(τ,Y n(τ))dτ (3) Example. Consider the initial value problem y′ = y, y(0) = 1, whose solution is y= et (using

The Picard method is also called the ‘sequential iteration’ or ‘fixed point’ method. It requires writing the system of equations in the form x = g ( x) where x is the vector of unknowns and g is the algorithm function used to compute x. The Picard method proceeds as …

good approximate solution to the differential equation. This makes this method of iteration an extremely powerful tool for solving differential equations! 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.

Existence and uniqueness: Picard’s theorem First-order equations Consider the equation y0 = f(x,y) (not necessarily linear). The equation dictates a value of y0 at each point (x,y), so one would expect there to be a unique solution curve through a given point.

We now give two quite simple examples to show that both parts of the theorem can fail if the Lipschitz condition is not satisfied. Example 1. Consider the equation y0 = −y2, with y(1) = 1, on the interval [−1,1]. Solving by elementary methods, we have − 1 y2 y0 = 1, 1 y = x+c. The condition y(1) = 1 selects the solution y = 1/x.

To find fixed points, approximation methods are often useful. See Figure 1, below, for an illustration of the use of an approximation method to find a fixed point of a function. To find a fixed point of the transformation T using Picard iteration, we will start with the function y 0(x) ⌘ y 0 and then iterate as follows: yn+1(x)=yn(x)+ Zx x0
