Sunto
Il lavoro è una rassegna di risultati recenti di convergenza q.o. della soluzioneu(x, t) dell’equazione di Schrödinger\(\Delta u = i\frac{{\partial u}}{{\partial t}}\) conu(x, 0)=f(x), dovef appartiene alla classe di Schwartz
. La convergenza q.o. è dedotta da stime quali
doveB è una ipersfera di
eH, denota lo spazio di Sobolev classico.
Summary
The paper is a survey of recent results on a.e. convergence of the solutionu(x, t) to the Schrödinger equation\(\Delta u = i\frac{{\partial u}}{{\partial t}}\) andu(x, 0)=f(x) wheref belongs to the Schwartz class
. A.e. convergence is established via estimates of the kind
whereB is a ball in
andH, denotes the classical Sobolev space.
