Do you mean in equation 10?
Is this what you would like:
$a(u, v) = \int{\Omega} \nabla u \cdot \nabla v~\mathrm{d}x + \int{\partial\Omega}\left[-(n \cdot\nabla u) v - (n \cdot \nabla v) u + \frac{\alpha}{h} uv\right] ~\mathrm{d}s$
and
$L(v) = \int{\Omega} fv~\mathrm{d}x + \int{\partial\Omega}\left[ -(n \cdot \nabla v) u_D + \frac{\alpha}{h} u_Dv\right]~\mathrm{d}s$
In the expression for $a(u, v)$ and $L(v)$ parentheses are missing under the integral sign.
