On the sufficiency of K-positivity for truncated compactly supported generalized moment problems
Examples and Counterexamples, 2021 Given a compact set K and a finite set of continuous basis functions, the truncated generalized K-moment problem asks for a characterization of all sequences that can be obtained as moments, with respect to the basis functions, of some nonnegative ...

Limitations on the Expressive Power of Convex Cones without Long Chains of Faces [PDF]
SIAM Journal on Optimization, 2019 A convex optimization problem in conic form involves minimizing a linear functional over the intersection of a convex cone and an affine subspace. In some cases, it is possible to replace a conic formulation using a certain cone, with a 'lifted' conic ...

Serrin’s type overdetermined problems in convex cones [PDF]
Calculus of Variations and Partial Differential Equations, 2018 We consider overdetermined problems of Serrin’s type in convex cones for (possibly) degenerate operators in the Euclidean space as well as for a suitable generalization to space forms. We prove rigidity results by showing that the existence of a solution

The geometry of hypothesis testing over convex cones: Generalized likelihood tests and minimax radii [PDF]
Annals of Statistics, 2017 We consider a compound testing problem within the Gaussian sequence model in which the null and alternative are specified by a pair of closed, convex cones. Such cone testing problem arise in various applications, including detection of treatment effects,

E-semigroups over closed convex cones [PDF]
Journal of operator theory, 2018 We initiate a study of E-semigroups over convex cones. We prove a structure theorem for E-semigroups which leave the algebra of compact operators invariant. Then we study in detail the CCR flows, E$_0$semigroups constructed from isometric representations,

Mathematics, 2020 Packing irregular 3D objects in a cuboid of minimum volume is considered. Each object is composed of a number of convex shapes, such as oblique and right circular cylinders, cones and truncated cones.

Large deviations for heavy-tailed random elements in convex cones [PDF]
, 2014 We prove large deviation results for sums of heavy-tailed random elements in rather general convex cones being semigroups equipped with a rescaling operation by positive real numbers.

Minkowski type theorems for convex sets in cones [PDF]
, 2020 Minkowski’s classical existence theorem provides necessary and sufficient conditions for a Borel measure on the unit sphere of Euclidean space to be the surface area measure of a convex body. The solution is unique up to a translation.
