Picard Numbers of Quintic Surfaces
An algebraic surface is defined as the set of points that satisfy a polynomial equation . The Picard number for an algebraic surface is a measure of the complexity of the curves on the surface. Algebraic surfaces with Picard numbers 1 to 45 are presented according to  and  containing parameters and .
More formally, the Picard number is the finite rank of the nonsingular complete variety of a sheaf cohomology group .
