内容简介:
Let E be a topological vector space and T: E --> E.
Then T is said to have boundedness stability property (in short, BSP)
iff for each x in E, if the sequence (T^n x)_{n=1} ^{\infinity} has a
bounded subsequence, then the whole sequence itself is bounded.
It is shown that in a finite dimensional space, all linear and affine
operators have BSP. Other results for affine operarors with compact
(resp. sub-normal) linear parts are also presented. If time permits, some
results of locally mean ergodic theorems for linear and affine operators
will also be discussed
