Controlling almost-invariant halfspaces in both real and complex settings

Adi Tcaciuc, Ben Wallis

If $T$ is a bounded linear operator acting on an infinite-dimensional Banach space $X$ , we say that a closed subspace $Y$ of $X$ of both infinite dimension and codimension is an al…

Constructing Banach ideals using upper $ℓ_{p}$ -estimates

Ben Wallis

Using upper $ℓ_{p}$ -estimates for normalized weakly null sequence images, we describe a new family of operator ideals $WD_{ℓ_{p}}^{(\infty, ξ)}$ with parameters $1\leq p…
