Pfaffian representations of quintics:  It is known that a general quintic (homogeneous form of degree five) in five variables can be expressed as the Pfaffian of a skew-symmetric matrix in only finitely many ways upto equivalence. I will discuss attempts at finding this number. This is joint work with A. Prabhakar Rao.
