On uniqueness cones, velocity cones andP-convexity

Abstract

Viene studiata l'unicita nel problema di Cauchy quando i coefficienti sono analitici. Il metodo e basato sull'uso dei coni di unicita. Un cono di unicita e il cono duale di un cono convesso e aperto di direzioni non-caratteristiche in un semi-spazio. I risultati ottenuti sono cosi generali che ci si puo chiedere se siano anche necessarie le trovate condizioni sufficienti per l'unicita nel problema di Cauchy. Vengono anche studiate la propagazione delle perturbazioni e la P-convessita.

Keywords

Initial value problems for linear higher-order PDEs, General existence and uniqueness theorems (PDE)
