Chow's theorem for real analytic Levi-flat hypersurfaces

In this article we provide a version of Chow's theorem for real analytic Levi-flat hypersurfaces in the complex projective space Pn, n≥2. More specifically, prove that hypersurface M⊂Pn, with singular set dimension at most 2n−4 and whose Levi leaves are contained algebraic hypersurfaces, is tangent to levels rational function Pn. As consequence, M semialgebraic set. We also foliation on Pn — immersed manifolds codimension one satisfying similar conditions all defined by level sets function.
