SUMMARY
Analytic continuation is a mathematical technique frequently utilized in Quantum Field Theory (QFT). It allows for the extension of analytic functions beyond their original domain. Specifically, if a function is analytic on an open subset of the complex numbers, it can be uniquely defined outside that set while maintaining its analytic properties across the entire complex plane. This concept bridges the gap between mathematics and physics, enhancing the understanding of complex functions in theoretical frameworks.
