Section 1.6 Existence and Uniqueness of Solutions. If \(x' = f(t, x)\) and \(x(t_0) = x_0\) is a linear differential equation, we have already shown that a solution exists and is unique. We will now take up the question of existence and uniqueness of solutions for all first-order differential equations.

Section 1.6 Existence and Uniqueness of Solutions. If \(x' = f(t, x)\) and \(x(t_0) = x_0\) is a linear differential equation, we have already shown that a solution exists and is unique. We will now take up the question of existence and uniqueness of solutions for all first-order differential equations. The existence and uniqueness of solutions will prove to be very important—even when we ...

ODE: Existence and Uniqueness of a Solution

existence of a solution to equation (7) and hence our differential equation (1). Uniqueness There are several ways to prove the uniqueness of the solution of the initial value problem (1). None of them are difficult. We work in the interval [0, β] defined above. Say U~(t) and ~V (t) are both solutions. Let W~ (t) := U~(t) − V~ (t).

Theorem 2 (Uniqueness). Suppose that both F(x;y) and @F @y (x;y) are continuous functions de ned on a re-gion R as in Theorem 1. Then there exists a number 2 (possibly smaller than 1) so that the solution y = f(x) to (*), whose existence was guaranteed by Theorem 1, is the unique solution to (*) for x0 2 < x < x0 + 2. x − 0 δ 2 x + 0 δ 2 0 ...

Example 3: Existence and Uniqueness Determine whether the following equation has guaranteed existence and uniqueness: There is no x, so we only have to consider restrictions on y. Since this is the case, we can go stright into the partial derivative of y: Solutions exist for all real numbers from negative to positive infinity, except for 0.

2.1. Uniqueness. We now establish the uniqueness of weak solutions. Theorem 2.4. Let ρ 0 ∈ L∞(Ω) be nonnegative. There exists at most one weak solution to problem (E1). Proof. Assume that there are two solutions to the problem: uand v. To prove uniqueness we use a version of the standard argument which is based on estimating
