We provide an example of a zero-dimensional compact metric space and its closed subspace such that there is no continuous linear extension operator for the Lipschitz pseudo…

On convex bodies of constant width
L. E. Bazylevych, M. M. Zarichnyi
We present an alternative proof of the following fact: the hyperspace of compact closed subsets of constant width in is a contractible Hilbert cube manifold. The proo…
