Core-collapse supernovae are among the most spectacular and complex
astrophysical phenomena, that can only be studied using numerical
simulations. Because of the strong gravitation of the newly-formed
neutron star, and the high velocities in the system, this phenomenon
has to be described within the framework of general relativity. This
thesis presents the first multi-dimensional simulations in which both
the dynamics of the stellar medium as well as the transport and the
interactions of neutrinos are treated in a general-relativistic
formulation. Among other things, we discuss the emitted gravitational
wave signals and the influence of relativistic effects on the
explosion mechanism, which is non-negligible according to our results.
