Normal Forms of second order Ordinary Differential Equations under Fibre-Preserving Maps
Wei Guo Foo, Julien Heyd, Joël Merker
We study the equivalence problem of classifying second order ordinary differential equations modulo fibre-preserving point transformations …
Holomorphic immersions of bi-disks into dimensional real hypersurfaces with Levi signature
Wei Guo Foo, Joel Merker
Inspired by an article of R. Bryant on holomorphic immersions of unit disks into Lorentzian CR manifolds, we discuss the application of Cartan's method to the question of the exist…
Rigid equivalences of -dimensional -nondegenerate rigid real hypersurfaces of constant Levi rank
Wei Guo Foo, Joel Merker, The-Anh Ta
We study the local equivalence problem for real-analytic () hypersurfaces which, in coordinates with $w =…
Differential -structures for equivalences of -nondegenerate Levi rank hypersurfaces
Wei Guo Foo, Joel Merker
The class of -nondegenerate constant Levi rank hypersurfaces is governed by Pocchiola's two primary invariants and . Their…
