Major results
One of the central tools in complex analysis is the line integral.
The line integral around a closed path of a function that is holomorphic everywhere inside the area bounded by the closed path is always zero, as is stated by the Cauchy integral theorem..
What is the purpose of complex analysis?
Complex analysis is used to solve the CPT Theory (Charge, Parity and Time Reversal), as well as in conformal field theory and in the Wick's Theorem.
Complex variables are also a fundamental part of QM as they appear in the Wave Equation.
String Theory: Indeed, Complex Analysis shows up in abundance in String theory..
Complex analysis is the study of complex numbers together with their derivatives, manipulation, and other properties.
Complex analysis is an extremely powerful tool with an unexpectedly large number of practical applications to the solution of physical problems.
