DOI: 10.1007/s10714-020-02716-9

Abstract: In the literature different concepts of compatibility between a projective structure $${\mathscr {P}}$$ P and a conformal structure $${\mathscr {C}}$$ C on a differentiable manifold are used. In particular compatibility in the sense of Weyl… read more here.
