Equivalence transformations applied to exterior calculus approach for finding symmetries: an example of non-Newtonian fluid flow
(JAN)
The 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 ...
Similarity transformations for partial differential equations
(MAR)
The importance of similarity transformations and their applications to partial differential equations is discussed. The theory has been presented in a simple manner so that it would be beneficial at the undergraduate level. ...
