Definition of "hypersurface orthogonal"
Hi all!
I'm not sure if the thread belongs more to General Relativity or Differential Geometry, but I guess the border is labile.
I've come across the term "hypersurface orthogonal" many times, but I still haven't found a clear definition. Apparently, if a flow is geodesic and irrotational, it is also hypersurface orthogonal, whatever this means.
Could you please give me a definition and explain how the hypersurface orthogonality is linked to the geodesy and irrotationality of a flow?
Thanks in advance!
