Functions that have this behavior will have a branch point, which is this point where as you go along 360º in a small circle around it, the function f (z) does not make a 360º arc. The function f (z) then becomes discontinuous, “it branches”.

WebFeb 1, 2012 · A function is complex differentiable if their partial derivatives for u and v exist and they satisfy the C-R-eq. Since the p.d. for u do not exist, f (z) is not complex differentiable (in z=0). This means that f (z) is not holomorphic in z=0. So just take the limit of f (z) approaching from the x and y-axis to show they limits are different. WebJul 6, 2024 · The two square roots (shown in red) for z (shown in blue).
