Abstract:LetX be a complex projective manifold of dimension n and let ε be an ample vector bundle of rank r. Let also τ = τ (X,ε) = min {t ∈ ℝ : KX + t det ε is nef} be the nef value of the pair (X, ε). In this paper we classify the pairs (X, ε) such that{$$ \tau (X,\epsilon) \geq \frac{n-2}{r}$$ Mathematics Subject Classification (2000)14J60; 14J40; 14E30
Keywords:Ample vector bundle  Extremal rays  Adjunction theory
