| Abstract: | The constraint from causality on transition amplitude in relativistic quantum mechanics (x, γ|0, o)=0 when γ2-|x|2<0 is proven for Dirac particle without and with interactions with external fields and for free scalar and vector particle in any (1+D)-dimensional Minkowskian space-time. |
