Riemann-Roch theorem for curves


Let C be a projective nonsingular curve over an algebraically closed field. If D is a divisor on C, then

(D)-(K-D)=deg(D)+1-g

where g is the genus of the curve, and K is the canonical divisor ((K)=g). Here (D) denotes the dimension of the http://planetmath.org/node/SpaceOfFunctionsAssociatedToADivisorspace of functions associated to a divisor.
