Cones of effective cycles on blow ups of projective spaces along rational curves

Benjamin Gould, Yeqin Liu

In this paper we examine the cones of effective cycles on blow ups of projective spaces along smooth rational curves. We determine explicitly the cones of divisors and 1- and 2-dim…

Nonexistence of exceptional bundles on $P^{3}$ with maximal possible ranks

Yeqin Liu

We prove that on $P^{3}$ there is no exceptional bundle with rank $r = 2 d^{2} + 1$ and degree $d$ for every $∣ d ∣ \geq 4$ . In particular, we find a new obstruction for the exist…
