Geometric Complexity Theory IV: nonstandard quantum group for the Kronecker problem

Jonah Blasiak, Ketan D. Mulmuley, Milind Sohoni

The Kronecker coefficient g_{λμν} is the multiplicity of the GL(V)\times GL(W)-irreducible V_λ\otimes W_μin the restriction of the GL(X)-irreducible X_νvia the natural map GL(V)\ti…
