Equivalence transformations applied to exterior calculus approach for finding symmetries: An example of non-Newtonian fluid flow

Pakdemirli M.Yürüsoy M.2025-04-102025-04-101999http://hdl.handle.net/20.500.14701/53447The exterior differential form approach for finding Lie-Point symmetries of differential equations is extended by implementing equivalence transformations to the formalism. The implementation is shown on a previously worked example of non-Newtonian fluid flow. Group classification of the equations are performed using this method. © 1998 Elsevier Science Ltd.
