Dec 8, 2015 at 8:22 | comment | added | username | @MathStudent I don't see what you mean. But 2.b is not optimal: if we allow $f\in H^1$ (as suggested) then it can be improved (by bootstrap) to get to $a$ in a slightly bigger space (I think). I'll edit it. | |
Dec 8, 2015 at 7:20 | comment | added | A random mathematician | This leads to the estimate ||a(x)u||H1(Ω)≤(1+C||a||W1,pn) ∥|f||L2(Ω), and not ||a(x)u||H1(Ω)≤C||a|| ∥|f||L2(Ω). The second inequality gives a better estimate for small a | |
