Schmidt rank and singularities

UDC 512.5 We revisit Schmidt's theorem connecting the Schmidt rank of a tensor with the codimension of a certain variety and adapt the proof to the case of arbitrary characteristic.&nbsp;We also find a sharper result of this kind for homogeneous polynomials, assuming the characteris...
