www.damtp.cam.ac.uk– the Cauchy–Riemann equations. It is also possible to show that if the Cauchy–Riemann equations hold at a point z, then f is differentiable there (subject to certain technical conditions on the continuity of the partial derivatives). If we know the real part u of an analytic function, the Cauchy–Riemann equations

If f is analytic and |f(z)| ≡ const then f ≡ const. Proof. If f(z) ≡ 0 there is nothing to prove. Suppose that u2 + v2 ≡ const > 0. Then 2uux + 2vvx = 0 and 2uuy ...

2 Complex Functions and the Cauchy-Riemann Equations
www.math.columbia.edu2 Complex Functions and the Cauchy-Riemann Equations 2.1 Complex functions In one-variable calculus, we study functions f(x) of a real variable x. Like-wise, in complex analysis, we study functions f(z) of a complex variable z2C (or in some region of C). Here we expect that f(z) will in general take values in C as well.

This is because, by CR equation u x = u y = v x = v y = 0. So by MVT of two variable calculus u and v are constant function and hence so is f.

web.mit.eduEquations (4.5) and (4.6) are known as the Cauchy-Riemann equations which appear in complex variable math (such as 18.075).

However, flow may or may not be irrotational.
