Second-Order PDEs in 3D with Einstein–Weyl Conformal Structure
Berjawi, S.; Ferapontov, E.V.; Kruglikov, Boris; Novikov, V.S. (Peer reviewed; Journal article, 2021)Einstein–Weyl geometry is a triple (D,g,ω) where D is a symmetric connection, [g] is a conformal structure and ω is a covector such that ∙ connection D preserves the conformal class [g], that is, Dg=ωg ; ∙ trace-free part ...
