The Lasserre hierarchy for equiangular lines with a fixed angle
David de Laat, Fabrício Caluza Machado, Willem de Muinck Keizer
We compute the second and third levels of the Lasserre hierarchy for the spherical finite distance problem. A connection is used between invariants in representations of the orthog…
