Query: The resolution property of algebraic surfaces   We prove that on separated algebraic surfaces every coherent sheaf is a
quotient of a locally free sheaf. This class contains many schemes that are
neither normal, reduced, quasiprojective or embeddable into toric varieties.
Our methods extend to arbitrary $2$-dimensional schemes that are proper over a
noetherian ring.
