Symmetry and Integrability of Equations of Mathematical Physics − 2022
Yegorchenko Iryna (Institute of Mathematics of NAS of Ukraine, Kyiv) A general solution of the eikonal equation for an arbitrary number of space variables Abstract:
We described a general solution of the eikonal equation
(uμuμ=1) for an arbitrary number of space variables in
parametric form. We used contact transformations for the construction
of this solution. We demonstrated a relation between this equation's
Lie symmetry solutions and the parametric general solution. We proved
that solutions described by the parametric formulas include solutions
that are not equivalent to the Lie symmetry solutions.
