Generalization of the algebraic method of group classification with application to nonlinear wave and elliptic equations
Olena O. Vaneeva, Alexander Bihlo, Roman O. Popovych
Enhancing and essentially generalizing previous results on a class of (1+1)-dimensional nonlinear wave and elliptic equations, we apply several new techniques to classify admissibl…

Equivalence groupoid and enhanced group classification of a class of generalized Kawahara equations
Olena Vaneeva, Olena Magda, Alexander Zhalij
Transformation properties of a class of generalized Kawahara equations with time-dependent coefficients are studied. We construct the equivalence groupoid of the class and prove th…
