Algebraic properties of Hermitian sums of squares

Abstract: We study real bihomogeneous polynomials r(z, z) in n complex variables for which r(z, z) z 2 is the squared norm of a holomorphic polynomial mapping. Such polynomials are the focus of the Sum of Squares Conjecture, which describes the possible ranks for the squared norm r(z, z) z 2 and has important implications for the study of proper holomorphic mappings between balls in complex Euclidean spaces of different dimension. Questions about the possible signatures for r(z, z) and the rank of r(z, z) z 2 can be ref… Show more
