Abstract: For any d Z and g, n 0 such that 2g - 2 + n > 0, denote by Picd, g, n the stack whose sections over a scheme S consist of flat and proper families : C S of smooth curves of genus g, with n distinct sections si : S C and a line bundle L of relative degree d over C. Morphisms between two such objects are given by cartesian diagrams C 2 // C S 1 // si II S s iU U such that si 1 = 2 si, 1 i n, together with an isomorphism 3 : L 2(L ). Picd, g, n is endowed w
