This is an announcement for the paper "Recognizing the topology of the space of closed convex subsets of a Banach space" by Taras Banakh, Ivan Hetman, and Katsuro Sakai.

Abstract: Let $X$ be a Banach space and $Conv_H(X)$ be the space of non-empty closed convex subsets of $X$, endowed with the Hausdorff metric $d_H$. We prove that each connected component of the space $Conv_H(X)$ is homeomorphic to one of the spaces: a singleton, the real line, a closed half-plane, the Hilbert cube multiplied by the half-line, the separable Hilbert space, or a Hilbert space of density not less than continuum.
