Frame independence of the fundamental length in relativistic quantum field theory

S. Nagamachi and E. Bruning<br/> Some time ago we proposed a relativistic quantum field theory with a fundamental length in terms of tempered ultrahyperfunctions [Bruning, E. and Nagamachi, S., Relativistic quantum field theory with a fundamental length, J.
