Exponential lower bounds on spectrahedral representations of hyperbolicity cones
Prasad Raghavendra, Nick Ryder, Nikhil Srivastava +1
The Generalized Lax Conjecture asks whether every hyperbolicity cone is a section of a semidefinite cone of sufficiently high dimension. We prove that the space of hyperbolicity co…
