Canonical Barriers on Convex Cones

Mathematics of Operations Research, 2014
On the interior of a regular convex cone K in n-dimensional real space there exist two canonical Hessian metrics, the one generated by the logarithm of the characteristic function, and the Cheng-Yau metric. The former is associated with a self-concordant logarithmically homogeneous barrier on K, the universal barrier.

Locally convex projective limit cones

Mathematica Slovaca, 2016
Using a family of ordered cones, we define a suitable order to investigate projective limit topologies for cones. Under the strict separation property, the projective limit cone topology is proved to be equivalent to some of the X-topologies embedded on ...

Tangent Cones and Convexity

Canadian Mathematical Bulletin, 1976
The study of general multiplier theorems (Kuhn-Tucker Conditions) for constrained optimization problems has led to extensions of the notion of a differentiable arc. Abadie [1], Varaiya [10], Guignard [5], Zlobec [11] and Massam [12] investigated the so called cone of tangent vectors to a point in a set for optimization purposes.

On Cone-Efficiency, Cone-Convexity and Cone-Compactness

SIAM Journal on Applied Mathematics, 1978
The properties of efficient (admissible) points of subsets of $R^n $ are discussed in the case when the space is ordered by a convex cone. It is demonstrated that the notion of cone-compactness (a generalization of compactness) is sufficient to guarantee the existence of an efficient point.

Solidity indices for convex cones

Positivity, 2011
The issue addressed in this work is how to measure the degree of solidity of a closed convex cone in the Euclidean space R n. One compares and establishes all sort of relations between the metric, the volumetric, and the Frobenius solidity indices.

On uniqueness cones, velocity cones andP-convexity

Annali di Matematica Pura ed Applicata, 1973
Viene studiata l'unicita nel problema di Cauchy quando i coefficienti sono analitici. Il metodo e basato sull'uso dei coni di unicita. Un cono di unicita e il cono duale di un cono convesso e aperto di direzioni non-caratteristiche in un semi-spazio.
