    (3). Today I will prove a version of Picard-Lindelof theorem, which gives us a sufficient condition for existence and uniqueness of a solution to a first.
    To understand uniqueness of solutions, consider the following examples.

    Induction on m. A is well defined.

    From Banach fixed-point theorem and the completeness ofit follows that there exists a unique function such thatand that is our unique solution to the initial value problem. Lemma 2: is bounded in the rectangle. Skip to content Greetings and salutations fellow math geeks! We have established that the Picard's operator is a contraction on the Banach spaces with the metric induced by the uniform norm.

    In this section, our aim is to prove several closely related results, all of which are occasionally called "Picard-Lindelöf theorem".

    This type of result is often used. Theorem The space C([a, b]) of continuous functions from [a, b] to We are now in a position to state and prove the Picard-Lindelöf Existence. Picard's Existence Theorem/Proof 1 Theorem; 2 Proof .

    It is also known as the Picard-Lindelöf Theorem or the Cauchy-Lipschitz Theorem.
    Views Read Edit View history. We define an operator between two functional spaces of continuous functions, Picard's operator, as follows:. From Banach fixed-point theorem and the completeness ofit follows that there exists a unique function such thatand that is our unique solution to the initial value problem.
