Factorization theorems of Backward Shifts and Nuclear Maps (Asuman Aksoy, CMC)

The theory of compact linear operators between Banach spaces has a classical core and is familiar to many. Perhaps lesser known is the factorization of compact maps through a closed subspace of \(c_0\) [2]. This factorization theorem has a number of important connections and consequences analogous to how the ideals of continuous linear operators factoring compactly through \(\ell^p\)-spaces \((1\leq p < \infty)\) (see [1] and the references therein). In this talk, even though hypercyclic operators are not compact, we consider operator ideals generated by hypercyclic backward weighted shifts and examine their factorization properties.
