ABSTRACT
We study some stronger forms of sensitivity, namely, -sensitivity and weakly
-sensitivity for non-autonomous discrete dynamical systems. We obtain a condition under which these two forms of sensitivity are equivalent. We also justify the difference between
-sensitivity and some other stronger forms of sensitivity through examples. We explore the relation between the
-sensitivity of the non-autonomous system
and autonomous system
, where
is a sequence of continuous functions converging uniformly to f. We also study the
-sensitivity of a non-autonomous system
, generated by a finite family of maps
and give an example showing that such non-autonomous systems can be
-sensitive, even when none of the maps in the family
is
-sensitive.
