Dynamics of weighted shifts on $ℓ^{p}$ -sums and $c_{0}$ -sums

Quentin Menet, Dimitris Papathanasiou

We investigate a generalization of weighted shifts where each weight $w_{k}$ is replaced by an operator $T_{k}$ going from a Banach space $X_{k}$ to another one $X_{k - 1}$ . We then look i…

Structure of sets of bounded sequences with a prescribed number of accumulation points

Quentin Menet, Dimitris Papathanasiou

For each vector $x \in ℓ^{\infty}$ , we can define the non-empty compact set $L_{x}$ of accumulation points of $x$ . Given an infinite subset $A$ of $N \ {1}$ , we c…
