Sažetak
In this report I'll describe shortly the so-called universal invariant ultraviolet regularization designed to preserve an internal symmetry of a quantum field theory in non-anomalous situations. It is universal in the sense that it is applicable to any model which can be formulated in terms of a trilinear interaction. It is invariant in the sense that it possesses as many nice intrinsic properties as are needed normally in order to derive Ward identities. As it has been proved in [1, 2] it works all right in gauge theories and in theories with global supersymmetry. One might think as well that contrary to dimensional regularization [3] it leads to no troubles in locally supersymmetric theories.
