  bibo_abstract:
  - We establish an isomorphism of complex K-theory of the moduli space  M  of “SL
    n​ ”-Higgs bundles of degree d and rank n (in the sense of Hausel–Thaddeus) and
    twisted complex K-theory of the orbifold  M  of PGL n​ -Higgs bundles of degree
    e, where (n,d)=(n,e)=1. Along the way, we prove the vanishing of torsion for H
    ∗ ( M ) and certain twisted complex K-theory groups of  M . We also extend Arinkin’s
    autoduality of compactified Jacobian to a derived equivalence between SL n​ -
    and PGL n​ -Hitchin systems over the elliptic locus. In the appendix, we develop
    a formalism of G-sheaves of spectra, generalising equivariant homotopy theory
    to a relative setting.@eng
