Thanks for the replies I wasn't very impressed by HRVOJE's paper "Time in relativistic and non relativistic quantum mechanics" because there are many assumptions leading to unphysical results. Related to nice Eugen's comments, that's true that relativistic second order Klein-Gordon...

KIM's article can be find typing " Lorentz-invariant Minimum uncertainty Product" directly in Google : it'worth seeing it ! Concernig direct demonstration of uncertainty relation covariance, I'd rather use the usual standard deviation formalism. In this context, both position and momentum are...

Thank you for the answer. It seems clear in terms of operator commutation relation. However, concidering uncertainty relations in terms of standard deviation produts (and not operators commutation), I can demonstrate this covariance directly using the usual Lorentz transformation relations...

Heisenberg's uncertainty relations are not covariant under Lorentz transformation. That means they don't have the same form in any inertial frame. So, how to modify these relations to leave them invariant in form under a Lorentz transformation ?
