Abstract
Generalizations of the three main equations of quantum physics, namely, the Schrödinger, Klein-Gordon, and Dirac equations, are proposed. Nonlinear terms, characterized by exponents depending on an index , are considered in such a way that the standard linear equations are recovered in the limit . Interestingly, these equations present a common, solitonlike, traveling solution, which is written in terms of the -exponential function that naturally emerges within nonextensive statistical mechanics. In all cases, the well-known Einstein energy-momentum relation is preserved for arbitrary values of .
