English abstract:
This thesis motivates and summarizes the construction of splitting schemes
for evolution equations. Further asymptotic correct local error estimators are proposed,
to adapt the step-size in time propagation and reduce total computation
time. Commutator free Magnus-type integrators are compared to splitting off the
time variable. The Methods are tested by three applications: Models for solar
cells, reaction-diffusion system by Gray-Scott and Schrödinger wave equations.
