| dc.description | We extend Reider's freeness criterion to normal surfaces of characteristic 0. Let Y be a normal surface. Let D be a nef divisor on Y such that K_Y+D is a Cartier divisor. Let x be a point on Y. If x is a base point of |K_Y+D| and D^2>δ_x (δ_x is determined by x, δ_x <= 4) then there exists a non zero effective divisor E on Y passing through x such that 0 <= DE <= δ_x /2, DE - δ_x /4 <= E^2 <= (DE)^2 / D^2, E^2 < 0 if DE=0. | |
