@lotus2019: Likely a bug in FullSimplify.

| Jul 3, 2023 at 8:58 | comment | added | lotus2019 | @user64494 Thank you for pointing out. However, I did not detect any obvious errors in my code, and my code obtained correct results when used on other complex functions. Very confused, I don't know where the problem is. I think there may be a problem with simplifying the square root of a complex function, but I haven't found it yet. | |

You asked "How to simplify -((I z)/Sqrt[Abs[z] - Re[z]]) to Sqrt[2 z]?" This is not true: compare the results of ComplexPlot[-((I z)/Sqrt[Abs[z] - Re[z]]), {z, -2 - 2*I, 2 + 2*I}] and ComplexPlot[Sqrt[2 z], {z, -2 - 2*I, 2 + 2*I}].

| Jul 2, 2023 at 15:02 | comment | added | lotus2019 | @Michael E2 I'm very sorry that there was no citation before and it has been edited. Thank you for the reminder and excellent code. | |
| Jul 2, 2023 at 14:57 | comment | added | lotus2019 | @Lacia Thank you for your suggestion. But this method has achieved correct results in other functions, so I think it should be a simplification problem. | |

Since the CR-equation holds on the whole plane except 0, why not just take the value on real or imaginary axis? e.g. u[x,0]+I v[x,0]
