Up to orthogonal transformation, a solid closed convex cone K in the Euclidean space Rn+1 is the epigraph of a nonnegative sublinear function f from Rn to R. This work explores the link between the geometric properties of K and the analytic properties of f. Part two of this article is published in this journal 19 (2012), Number 1.
Keywords: Convex cone, epigraphical cone, sublinear function, inradius of a cone, solidity, pointedness, angular spectrum.
