We study the complexity of computing Kronecker coefficients {g (\lambda,\mu,\nu)}. We give explicit bounds in terms of the number of parts {\ell} in the partitions, their largest part size N and the smallest second part M of the three partitions. When M = O (1), i.e., one of the partitions is hook-like, the bounds are linear in log N ...
