On semidefinite programming characterizations of the numerical radius and its dual norm

Shmuel Friedland, Chi-Kwong Li

We state and give self contained proofs of semidefinite programming characterizations of the numerical radius and its dual norm for matrices. We show that the computation of the nu…

Complexity of Geometric programming in the Turing model and application to nonnegative tensors

Shmuel Friedland, Stéphane Gaubert

We consider a version of geometric programming problem consisting in minimizing a function given by the maximum of finitely many log-Laplace transforms of discrete nonnegative meas…

Haagerup bound for quaternionic Grothendieck inequality

Shmuel Friedland, Zehua Lai, Lek-Heng Lim

We present here several versions of the Grothendieck inequality over the skew field of quaternions: The first one is the standard Grothendieck inequality for rectangular matrices,…

Infimum of a matrix norm of A induced by an absolute vector norm

Shmuel Friedland

We characterize the infimum of a matrix norm of a square matrix A induced by an absolute norm, over the fields of real and complex numbers. Usually this infimum is greater than the…

Quantum Optimal Transport

Sam Cole, Michał Eckstein, Shmuel Friedland +1

We analyze a quantum version of the Monge--Kantorovich optimal transport problem. The quantum transport cost related to a Hermitian cost matrix is minimized over the set of all…

Upper bounds for the spectral norm of symmetric tensors

Shmuel Friedland

The maximum of the absolute value of a real homogeneous polynomial of degree on the unit sphere corresponds to the spectral norm of the induced real -symmetric tensor $…
