SUMMARY
The Cauchy's differintegral formula is expressed as \(\frac{d^n}{dz^n}f(z_0)=\frac{n!}{2\pi i!}\oint_{\gamma}\frac{f(z)}{(z-z_0)^{n+1}}dz\). This formula is valid when the derivative is taken with respect to \( \bar{z} \) as well, represented by \(\frac{d^n}{d\bar{z}^n}f(z_0)\). The discussion raises the question of the validity of the integral when computed with respect to \( \bar{z} \), prompting a request for proof. Participants express uncertainty regarding the proof of this concept.
