Probabilistic bounds on best rank-one approximation ratio

Khazhgali Kozhasov, Josué Tonelli-Cueto

We provide new upper and lower bounds on the minimum possible ratio of the spectral and Frobenius norms of a (partially) symmetric tensor. In the particular case of general tensors…

Positivity Certificates via Integral Representations

Khazhgali Kozhasov, Mateusz Michałek, Bernd Sturmfels

Complete monotonicity is a strong positivity property for real-valued functions on convex cones. It is certified by the kernel of the inverse Laplace transform. We study this for n…
