WebOct 21, 2016 · We introduce tropical spectrahedra, defined as the images by the nonarchimedean valuation of spectrahedra over the field of real Puiseux series. We provide an explicit polyhedral characterization of generic tropical spectrahedra, involving principal tropical minors of size at most 2. One of the key ingredients is Denef-Pas quantifier … WebMay 18, 2024 · Spectrahedra, the solution sets of linear matrix inequalities (LMIs), play a central role in semidefinite programming, convex optimization, and in real algebraic geometry [8, 34].They also figure prominently in the study of determinantal representations [10, 35, 41], the solution of the Lax conjecture [], and in the solution of the Kadison–Singer … pinot chengen
