Interpolator symmetries and new Kalton-Peck spaces

Diagrams generated by three interpolators in an abstract Kalton-Montgomery complex like interpolation scheme. We will consider in detail the case of the first three Schechter interpolators associated to the usual Calderón complex interpolation method in two especially interesting cases: weighted $\ell_2$ spaces, i.e., interpolation pairs $(\ell_2(w^{-1}), \ell_2(w))_θ$, and $\ell_p$ spaces, i.e., the interpolation pair $(\ell_\infty, \ell_1)_θ$, both at $θ=1/2$.

Higher order derivatives of analytic families of Banach spaces

We show that the Rochberg spaces induced by complex interpolation form themselves complex interpolation scales, obtain the interpolated spaces and associated derivations. We present our results in the context of analytic families of Banach spaces and study the problem of determining the Rochberg spaces induced by these new families.
