Query: A generalised Green-Julg theorem for proper groupoids and Banach
  algebras   The Green-Julg theorem states that K_0^G(B) is isomorphic to K_0(L^1(G,B))
for every compact group G and every G-C*-algebra B. We formulate a
generalisation of this result to proper groupoids and Banach algebras and
deduce that the Bost assembly map is surjective for proper Banach algebras.
  On the way, we show that the spectral radius of an element in a C_0(X)-Banach
algebra can be calculated from the spectral radius in the fibres.
