Popis: For several important systems of the λ-cube we study the time-complexity of type conversion. Non-elementary lower bounds are given for the type-conversion problem for λ\(\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{\omega }\)and λP and hence for the systems that include one of these systems. For λ\(\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{\omega }\)and λP a super-exponential upper bound is given to the length of reduction sequences starting from types that are legal in these systems.
