Geometry of syzygies of sheaves on $P^{2}$ via interpolation and Bridgeland stability

Manuel Leal, Cesar Lozano Huerta, Tim Ryan

We show that the minimal free resolution of a general semi-stable sheaf $U$ on $P^{2}$ contains a subcomplex that determines an extremal ray of the cone of effective divisor…

Smooth Surfaces with Maximal Lines

Janet Page, Tim Ryan, Karen E. Smith

We prove that a smooth projective surface of degree $d$ in $P^{3}$ contains at most $d^{2} (d^{2} - 3 d + 3)$ lines. We characterize the surfaces containing exactly $d^{2} (d^{2} - 3 d + 3)$ lin…
