SUMMARY

This discussion focuses on evaluating two complex integrals along a parabolic contour defined by the equation \(y = 1 - x^2\). The integrals in question are \(\int_{i}^{1} e^{(i\log\bar{z})} dz\) and \(\int_{i}^{1} \log\bar{z} dz\). The user expresses uncertainty about handling the logarithmic term \(\log\bar{z}\) and the argument \(\arg\bar{z}\). The proposed parameterization of the contour as \((t, 1-t^2)\) is discussed, with numerical evaluation suggested as a viable approach for both integrals.

PREREQUISITES
  • Understanding of complex analysis, specifically integrals and contours.
  • Familiarity with logarithmic functions in the complex plane.
  • Knowledge of parameterization techniques for curves.
  • Experience with numerical evaluation methods for integrals.
NEXT STEPS
  • Study the properties of complex logarithms and their branches.
  • Learn about parameterizing curves in complex analysis.
  • Explore numerical integration techniques for complex functions.
  • Investigate the use of the argument function in complex logarithms.
USEFUL FOR

Mathematicians, students of complex analysis, and anyone interested in evaluating complex integrals along non-linear contours.

How to evaluate the following two complex integrals along a parabolic contour?
I need to evaluate the following two complex integrals along a parabolic contour, and I am not sure I know how to deal with the ##\log\bar{z}## in both cases. Since for the log term, I do not know how to find ##i\arg\bar{z}##. Also, if I used either the line integral approach vs parameterize the contour as ##(t, 1-t^2)##. Would I get the same answer?

##\int_{i}^{1}\ e^{(i\log\bar{z})} dz##

##\int_{i}^{1} \log\bar{z}dz## both on the contour ##y=1-x^2##

Thank you in advance

Say
z=r e^{i\theta}
The first integral would be
\int_0^1 dt e^{i \log r(t)}e^{\theta(t)}
where
r(t)=\sqrt{t^4-t^2+1}
\theta(t)=arctan\frac{1-t^2}{t}
Numerical evaluation seems applicable. The second integral would be
\int_0^1 dt (\log r (t)- i\theta(t))
 
@anuttarasammyak I just saw your reply. For some reasons, I did not get the notifications that you made a reply. Thank you so much for your solutions. I really appreciate it.
