Abstract We study Le Potier's strange duality conjecture on P 2. We focus on the strange duality map S D c n r, d which involves the moduli space of rank r sheaves with trivial first Chern class and second Chern class n, and the moduli space of 1-dimensional sheaves with determinant O P 2 (d) and Euler characteristic 0. By using tools in quiver representation theory, we show that S D c n r, d is an isomorphism for r= n or r= n− 1 or d≤ 3, and in general S D c n r, d is injective for any n≥ r> 0 and d> 0.
