The smoothness assumption in the theorem can be relaxed, as well: for a(projective) curve over an algebraically closed field, all of whose local rings are Gorenstein rings, the same statement as above holds, provided that the geometric genus as defined above is replaced by the arithmetic genus ga, defined as g a:= dim k H 1( C, O C).{\displaystyle g_{ a}:=\ dim_{ k}H^{ 1}( C,{\ mathcal{ O}}_{ C}).} For smooth curves, the geometric genus agrees with the arithmetic one.
