Title: Approximate Conditional Symmetries of PDEs

Following a recently introduced approach to approximate Lie symmetries which is consistent with the principles of perturbative analysis of differential equations containing small terms, the case of approximate Q-conditional symmetries is considered. An application of the method to a hyperbolic variant of a nonlinear reaction-diffusion-convection equation is exploited. Some approximate solutions are explicitly constructed.
