Exceptional pairs on del Pezzo surfaces and spaces of compatible Feigin-Odesskii brackets

Alexander Polishchuk, Eric Rains

We prove that for every relatively prime pair of integers $(d, r)$ with $r > 0$ , there exists an exceptional pair $(O, V)$ on any del Pezzo surface of degree 4, such that $V…

Algebra of global sections of $ψ$ -bundles on $M ˉ_{0, n}$

Alexander Polishchuk, Eric Rains

We consider the $Z^{n}$ -graded algebra of global sections of line bundles generated by the standard line bundles $L_{1}, \dots, L_{n}$ on $M ˉ_{0, n}$ . We find a simple prese…
