WitrynaThe theorem allows us to make predictions on the length of the interval (that is h is less than or equal to the smaller of the numbers a and b/M). In most cases the lower … WitrynaHere we present the main results of this paper: existence, uniqueness and regularity of weak solutions. For the notion of weak solutions and relevant notation such as Tailp−1,sp,sp,we refer to Sect. 2. In the theorem below, p∗ refers to the Sobolev exponent, see (2.1). Theorem1.1 (Existence and uniqueness) Suppose 1 < p < ∞, 0 …
LECTURE 4: EXISTENCE AND UNIQUENESS THEOREM Existence …
In mathematics – specifically, in differential equations – the Picard–Lindelöf theorem gives a set of conditions under which an initial value problem has a unique solution. It is also known as Picard's existence theorem, the Cauchy–Lipschitz theorem, or the existence and uniqueness theorem. The … Zobacz więcej The proof relies on transforming the differential equation, and applying Banach fixed-point theorem. By integrating both sides, any function satisfying the differential equation must also satisfy the integral equation Zobacz więcej Nevertheless, there is a corollary of the Banach fixed-point theorem: if an operator T is a contraction for some n in N, then T has a unique fixed point. Before applying this theorem to … Zobacz więcej • Mathematics portal • Frobenius theorem (differential topology) • Integrability conditions for differential systems Zobacz więcej • "Cauchy-Lipschitz theorem".

The Peano existence theorem shows only existence, not uniqueness, but it assumes only that f is continuous in y, instead of Lipschitz continuous. For example, the right-hand side … Zobacz więcej Witryna*Note 1: The existence and uniqueness theorems stated above are local in nature since the interval, jx x 0j , where solution exists may be smaller than the original interval, jx x 0j a, where f(x;y) is de ned.
