In modern times, it has become very popular through a new boost from complex dynamics and the pictures of fractals produced by iterating holomorphic functions. Another important application of complex analysis is in string theory which examines conformal invariants in quantum field theory.
Complex analysis has become increasingly popular today thanks to its use in generating intricate fractal patterns from holomorphic functions. It also plays a crucial role in string theory, where it helps analyze conformal invariants within the framework of quantum field theory.
