“…This is immediate from the fact that a pointed neighborhood of an interior point cannot be contractible. Hence the interior of a CAT(0) surface is GCBA in the sense of Lytchak and Nagano [LN18].…”

“…Although we do not have definite bounds in general, a compactness argument may verify (some of) these conditions under appropriate assumptions (such as the geodesic completeness, in other words, the infinite extendability of geodesics). We remark that local structures of CAT(0)-spaces are investigated in [Kl] as well as in a famous unpublished paper by Otsu-Tanoue ("The Riemannian structure of Alexandrov spaces with curvature bounded above") and Lytchak-Nagano's recent preprints [LN1,LN2].…”
