The Role of Three-dimensional Subalgebra in the Analysis of Hidden Symmetries of Differential Equations
Mladen Nikolic, Milan Rajkovic
Some new properties of symmetries that disappear as point symmetries after the first reduction of order of an ODE and reappear after the second are analyzed from the aspect of thre…
