Lie symmetry method for a nonlinear heat-diffusion equation
We investigate the nonlinear heat-diffusion equation $C(u)u_t = (K(u)u_x)_x$, where $C(u)$ and $K(u)$ are coefficients that depend on u. By applying the classical Lie symmetry method, we determine the admitted Lie point symmetries and compute the corresponding infinitesimal generators according to t
