Geometric invariants of the horizontal velocity gradient tensor and their dynamics in shallow water flow

Divergence and vorticity are well known to be geometrically invariant quantities in that their mathematical forms are independent of the orientation of the coordinate axes. Various other functions of the elements of the horizontal velocity gradient tensor are invariants in the same sense: examples a...
