Global propagation of analyticity and unique continuation for semilinear conservative PDEs
Camille Laurent, Cristóbal LoyolaWe review some recent results in which we develop a new method for proving global unique continuation for some conservative PDEs. The main tool is to prove some global propagation of analyticity. We first present some known results on the subject. Then, we sketch the abstract method we use, which relies on some finite determining mode property. We give applications to semilinear wave, plates and Schrödinger equation.
