What precisely does the notation $frac {partial h} {partial z}$ mean in this context?
$begingroup$
I am given the following problem.
Let $Ωsubset mathbb{C} $ and let $h in C^1(Ω)$ be such that $frac {partial h} {partial z}=0$. Show that $h(z)=overline {f(z)}$ for some $f$ analytic in $Ω$.
The $frac {partial h} {partial z}$ notation is mysterious to me. But, after looking at this, I have a guess as to what it means.
Write $h(x+iy)=u(x,y)+iv(x,y).$ Then $frac {partial h} {partial z}=frac {[u_x+iv_x]-i[u_y+iv_y]} 2=frac {u_x+v_y+iv_x-iu_y} 2$. Is this interpretation correct?

It's just the ordinary derivative $frac{partial}{partial z} = frac{1}{2}left(frac{partial}{partial x} - frac{partial}{partial y}right)$.
