摘要
The aim of this article is to obtain restrictions on complex orientations of dividing real J-curves of almost-complex manifolds. This problem comes from real algebraic geometry and the main result is a congruence generalising Arnol'd, Rokhlin, Mishachev, Zvonilov and Mikhalkin 's previous results. This congruence is obtained with a canonical map defined on homology groups of dimension half the dimension of the manifold with coefficients in , with values in .
