"Invariant subspaces for Banach space operators and Reflexivity"




Onur Yavuz



Abstract: I will first talk about an invariant subspace result by Ambrozie and Muller for Banach space operators whose spectrum contains the unit circle. Then I will describe briefly how this result can be extended to operators with a multiply connected spectrum. If time permits, I will discuss the corresponding reflexivity problem.


Tea and cookies will be served before the seminar.
