Query: Von Neumann's inequality for tensors   For two matrices in $\mathbb R^{n_1\times n_2}$, the von Neumann inequality
says that their scalar product is less than or equal to the scalar product of
their singular spectrum. In this short note, we extend this result to real
tensors and provide a complete study of the equality case.
