*On a parabolic problem with nonlinear Newton boundary conditions *

Comment.Math.Univ.Carolinae 43,3 (2002) 429-455. **Abstract:**The paper is concerned with the study of a parabolic initial-boundary value problem with nonlinear Newton boundary condition considered in a two-dimensional domain. The goal is to prove the existence and uniqueness of a weak solution to the problem in the case when the nonlinearity in the Newton boundary condition does not satisfy any monotonicity condition and to analyze the finite element approximation.

**Keywords:** parabolic convection-diffusion equation, nonlinear Newton boundary condition, Galerkin method, compactness method, finite element approximation, error estimates
