Abstract
The ground-state properties of superheavy nuclei are investigated within
various parametrisations of relativistic and nonrelativistic
nuclear mean-field models. The heaviest known even-even nuclei
starting with are used as a benchmark to estimate
the predictive power of the models and forces. From that starting point,
deformed doubly magic nuclei are searched in the region
and
