A -quadrilateral cosine characterization of Aleksandrov spaces of curvature bounded above
I. D. Berg, Igor G. Nikolaev
In this note, we extend the main results of our paper on quasilinearization and curvature of Aleksandrov spaces of curvature to curvature bounds other than . For non-zer…

Integral-Geometric Formulas for Perimeter in S^2, H^2, and Hilbert Planes
Ralph Alexander, I. D. Berg, Robert L. Foote
We develop two types of integral formulas for the perimeter of a convex body K in planar geometries. We derive Cauchy-type formulas for perimeter in planar Hilbert geometries. Spec…
