Popis:	Relativistic invariance in Euclidean formulations of quantum mechanics is discussed. Relativistic treatments of quantum theory are needed to study hadronic systems at sub-hadronic distance scales. Euclidean formulations of relativistic quantum mechanics have some computational advantages. In the Euclidean representation the physical Hilbert space inner product is expressed in terms of Euclidean space-time variables with no need for any analytic continuation. The identification of the complex Euclidean group with the complex Poincar\'e group relates the infinitesimal generators of both groups. In this work explicit representations of the Poincar\'e generators in Euclidean space-time variables for all positive-mass positive-energy irreducible representations of the Poincar\'e group are derived. The commutation relations are checked, both hermiticity and self-adjointness are established, and reflection positivity of the kernels is verified. Comment: 23 pages
