In this paper, we determine which blow-ups X of $Pn at general points are log Fano, that is, when there exists an effective Q-divisor Δ such that-(KX+Δ) $ is ample and the pair (X,Δ) is klt. For these blow-ups, we produce explicit boundary divisors Δ making X log Fano.

Abstract
In this paper, we determine which blow-ups X of $Pn at general points are log Fano, that is, when there exists an effective Q-divisor Δ such that-(KX+Δ) $ is ample and the pair (X,Δ) is klt. For these blow-ups, we produce explicit boundary divisors Δ making X log Fano.File in questo prodotto:
