Multidimensional exact solutions to a quasilinear parabolic equation with anisotropic heat conductivity
È. I. Semenov Institute of System Dynamics and Control Theory, Siberian Branch of the Russian Academy of Sciences
Abstract:
We prove invariance of a quasilinear parabolic equation with anisotropic heat conductivity in the three-dimensional coordinate space under some equivalence transformations and present some explicit formulas for these transformations. We consider nontrivial reductions of the equation to similar equations of less spatial dimension. Using these results, we construct new exact multidimensional solutions to the equation which depend on arbitrary harmonic functions.
Keywords:
quasilinear parabolic heat equation, Liouville equation, multidimensional exact solution, equivalence transformation, anisotropy, conjugate harmonic function.
