Spectrahedral shadows and completely positive maps on real closed fields

Journal of the European Mathematical Society (Print), 2022
In this article we develop new methods for exhibiting convex semialgebraic sets that are not spectrahedral shadows. We characterize when the set of nonnegative polynomials with a given support is a spectrahedral shadow in terms of sums of squares.

On equality of complete positivity and complete copositivity of positive map

2022
Summary: In this paper we construct a \(2\)-positive map from \(\mathcal{M}_4(\mathbb{C})\) to \(\mathcal{M}_5(\mathbb{C})\) and state the conditions under which the map is positive and completely positive (copositivity of positive). The construction allows us to create a decomposable map, where the Choi matrix of complete positivity is equal to the ...
