Theorem

Picard-Lindelof Theorem

Analysis

The Picard-Lindelof Theorem, also called the Cauchy-Lipschitz Theorem, gives conditions under which an ordinary differential equation with an initial value has a unique solution defined on some interval around the initial point, requiring that the equation's right-hand side be continuous and satisfy a Lipschitz condition. Named for Emile Picard and Ernst Lindelof, it is the standard existence-and-uniqueness result taught in every first course on differential equations.

Facts
Statement
For an ordinary differential equation with an initial value, if the right-hand side is continuous and Lipschitz continuous in the dependent variable near the initial point, a unique solution exists on some interval around that point. 2
