摘要：
The first Chern class of an initialized rank 2 bundle determines its level of stability. We determine bounds for numbers c(1) > 0 such that, on a general surface X subset of P-3 of degree d >= .4, there exists a rank 2 indecomposable (stable) aCM bundle E on X, with first Chern class c(1)(E) = c(1).
