Geometric rank of tensors and subrank of matrix multiplication
The rank of a matrix is a parameter of obvious importance, so it is natural to wonder what the right definition is for the rank of a higher-dimensional matrix -- that is, of a tensor (which can be thought of as a $d$-dimensional array of elements of a field $\mathbb F$). This question turns out not...
