Title: Sinkhorn and power method for tensors with positive entries
Abstract: For positive matrices, the power method and the Sinkhorn method have in common that their convergence can be analysed with tools of the nonlinear Perron-Frobenius theory such as the Hilbert projective metric and the Birkhoff-Hopf theorem. We present a generalization of these tools for positive tensors of any order and discuss the convergence of the corresponding higher order power method and higher order Sinkhorn method.
