abstract = {<p style="text-align: justify;">The weak Galerkin (WG) method is a nonconforming numerical method for
solving partial differential equations. In this paper, we introduce the WG method for
elliptic equations with Newton boundary condition in bounded domains. The Newton
boundary condition is a nonlinear boundary condition arising from science and engineering applications. We prove the well-posedness of the WG scheme by the monotone operator theory and the embedding inequality of weak finite element functions.
The error estimates are derived. Numerical experiments are presented to verify the
theoretical analysis.</p>},
