Similarity reductions for a nonlinear diffusion equation
Maria Luz Gandarias, P. Venero, José Ramírez-Labrador
Similarity reductions and new exact solutions are obtained for a nonlinear diffusion equation. These are obtained by using the classical symmetry group and reducing the partial dif…

Charged Free Fermions, Vertex Operators and Classical Theory of Conjugate Nets
Adam Doliwa, Manuel Manas, Luis Martinez Alonso +2
We show that the quantum field theoretical formulation of the -function theory has a geometrical interpretation within the classical transformation theory of conjugate nets. In…

Classical and nonclassical symmetries of a generalized Boussinesq equation
Maria Luz Gandarias, M. S. Bruzón
We apply the Lie-group formalism and the nonclassical method due to Bluman and Cole to deduce symmetries of the generalized Boussinesq equation, which has the classical Boussinesq…
