Strongly essential flows on irreducible parabolic geometries (Q2821683)

The paper is devoted to the study of irreducible parabolic structures, which include conformal semi-Riemannian, projective, almost \(c\)-projective, almost quaternionic and almost Grassmannian geometries. Namely, the paper addresses the local geometry of parabolic structures equipped with \(1\)-parameter families \(\varphi^t\) of local automorphisms with a fixed point \(x_0\) and trivial differential at \(x_0\).NEWLINENEWLINEIn this context, the authors find several new results, recover old ones and discuss interesting open problems.
