Ever since their definition in the 1930s, as multiplicities of irreducible symmetric group representations in the tensor product of two others, the Kronecker coefficients have eluded our attempts to describe them combinatorially or to compute them efficiently. Computational complexity gives us the tools to formalize that mysteriousness. We will discuss their "hardness" and show how to obtain some effective bounds despite the lack of efficient formulas.
