The proof relies on constructing a new functional, which includes both the initial displacement and the initial velocity: with sign preserving property of the new functional we show the existence of global weak solutions.eninfo:eu-repo/semantics/openAccessKlein-Gordon EquationPotential WellGlobal ExistenceHigh Energy Initial DataArticle28510731079WOS:0003447754000152-s2.0-8490822714510.2298/FIL1405073PQ3Q2
