Remarks on Chebyshev coordinates
Yu. Burago, S. Ivanov, S. Malev
Some results on existence of global Chebyshev coordinates on a Riemannian manifold or, more generally, on Aleksandrov surface are proved. For instance, if the positive and the nega…

Interpolation of subspaces and applications to exponential bases in Sobolev spaces
S. Ivanov, N. Kalton
We give precise conditions under which the real interpolation space [Y_0,X_1]_{s,p} coincides with a closed subspace of the corresponding interpolation space [X_0,X_1]_{s,p} when Y…
