- W1669702945 abstract "Consider the blow up $pi: widetilde{X} to X$ of a rational surface $X$ at a point. Let $widetilde{V}$ be a holomorphic bundle over $widetilde{X}$ whose restriction to the exceptional divisor equals ${cal{O}(j) oplus {cal O}(-j)$ and define $V =(pi_*widetilde{V})^{vee vee}.$ Friedman and Morgan gave the following bounds for the second Chern classes $j leq c_2(widetilde{V}) - c_2(V) leq j^2.$ We show that these bounds are sharp." @default.
