Lifts of Non-compact Convex Sets and Cone Factorizations
Chu Wang, Lihong Zhi
In this paper we generalize the factorization theorem of Gouveia, Parrilo and Thomas to a broader class of convex sets. Given a general convex set, we define a slack operator assoc…

Semidefinite representations of non-compact convex sets
Feng Guo, Chu Wang, Lihong Zhi
We consider the problem of the semidefinite representation of a class of non-compact basic semialgebraic sets. We introduce the conditions of pointedness and closedness at infinity…

A certificate for semidefinite relaxations in computing positive dimensional real varieties
Yue Ma, Chu Wang, Lihong Zhi
For an ideal I with a positive dimensional real variety, based on moment relaxations, we study how to compute a Pommaret basis which is simultaneously a Groebner basis of an ideal…
