Lightlike Einstein hypersurfaces in Lorentzian manifolds with constant curvature

ATINDOGBE COMLAN CYRIAQUE [1], EZIN JEAN-PIERRE [2], TOSSA JOEL [3],

We study and characterize a class of lightlike hypersurfaces in Lorentzian manifolds of constant curvature, that satisfy Einstein equation. Integrabi [...]
