Following the approach of Gromov and Witten, we define invariants under
deformation of stongly semipositive real symplectic six-manifolds. These
invariants provide lower bounds in real enumerative geometry, namely for the
number of real rational J-holomorphic curves which realize a given homology
class and pass through a given real configuration of points.Comment: 18 pages, 1 figure, main result restricted to dimension six, see
