Abstract

We obtain an infinite-dimensional cone of singular twisted Hilbert spaces Z(φ)Z(\varphi) which are isomorphic to their duals but not to their conjugate duals. We do that by showing that the subset of all bi-Lipschitz maps from [0,)[0, \infty) to R\mathbb{R} is coneable. We also provide a characterization of the Kalton-Peck space among all twisted Hilbert spaces of the form Z(φ)Z(\varphi), which gives a partial answer to a conjecture of F. Cabello S\'anchez and J. Castillo.
