The function... (1) ... is the principal branch of the function . It is analytic in tha whole complex plane with the exception of where it has a branch point... Kind regards

Setting and we have ... (1) ... so that is... (2) The Cauchy-Riemann condition are then satisfied in the whole complex plane with the only exception of the point ... Kind regards
