The proof of key carleman estimate
WebbThe proofs are based on a Carleman estimate where the weight function depends on H. 1. Introduction and main results Let Ω ⊂ Rn be a bounded domain with smooth boundary and H = (h1 , ..., hn ) ∈ (C 1 (Ω))n . Let (x·y) and x denote the scalar product of x, y ∈ Rn and the norm of x ∈ Rn , respectively. WebbOur key is a classical Carleman estimate for a single parabolic equation with singular weight function by Imanuvilov [5]. The linearized mean field game equations (1.3) have two ... In Section 2, we prove a Carleman estimate (Theorem 3) for the linearized mean field game equations and complete the proof of Theorem 1.

Webb21 juni 2010 · The authors prove Carleman estimates for the Schrödinger equation in Sobolev spaces of negative orders, and use these estimates to prove the uniqueness in the inverse problem of determining L p -potentials. An L 2 -level observability inequality and unique continuation results for the Schrödinger equation are also obtained.

First, we obtain equations for functions Dk t (u 1 − u 2), k= 3,4, because these equations are more convenient to work with. This is done in Section 2. Also, in this section we formulate our key Carleman estimate for a hyperbolic operator (Lemma 2.1) and two more lemmata. Next, we prove three new Carleman estimates.
