Border Ranks of Positive and Invariant Tensor Decompositions: Applications to Correlations
Andreas Klingler, Tim Netzer, Gemma De les Coves
The matrix rank and its positive versions are robust for small approximations, i.e. they do not decrease under small perturbations. In contrast, the multipartite tensor rank can co…

Many bounded versions of undecidable problems are NP-hard
Andreas Klingler, Mirte van der Eyden, Sebastian Stengele +2
Several physically inspired problems have been proven undecidable; examples are the spectral gap problem and the membership problem for quantum correlations. Most of these results…
