Wrońskian factorizations and Broadhurst–Mellit determinant formulae
Drawing on Vanhove's contributions to mixed Hodge structures for Feynman integrals in two-dimensional quantum field theory, we compute two families of determinants whose entries are Bessel moments.Via explicit factorizations of certain Wrońskian determinants, we verify two recent conjectures proposed by Broadhurst and Mellit, concerning determinants of arbitrary sizes.With some extensions …
