摘要
The compact curves of an intermediate Kato surface S form a basis of H-2(S, Q). We present a way to compute the associated rational coefficients of the first Chern class c(1) (S). We get in particular a simple geometric obstruction for c(1) (S) to be an integral class, or equivalently index (S) = 1. In the final part we discuss relations with some recent work of Dloussky (2011) and Oeljeklaus and Toma (2009).
