abstract
We classify the faces of copositive and completely positive cones over a second-order cone and investigate their dimension and exposedness properties. Then we compute two parameters related to chains of faces of both cones. At the end, we discuss some possible extensions of the results with a view toward analyzing the facial structure of general copositive and completely positive cones.

An inexact subgradient algorithm achieves O(ε^{-2}) iteration complexity for ε-accurate solutions to copositive programs while allowing inexact solves of NP-hard quadratic subproblems and providing a sufficient condition for non-complete positivity.
