Unlike real numbers, which can be visualized as points on a number line, complex numbers have a two-dimensional nature. They can be visualized as points in a complex plane, where the real part corresponds to the horizontal axis and the imaginary part corresponds to the vertical axis.

Complex analysis explores the properties of functions defined on complex numbers, uncovering their behavior and characteristics. It provides a powerful framework for solving various problems in mathematics and physics, such as fluid dynamics, electromagnetism, quantum mechanics, and more.

Why is Complex Analysis Important?

Complex analysis plays a crucial role in many areas of mathematics and science. Here are a few key reasons why it is considered an essential field of study:

1. Understanding Elementary and Analytic Functions

Complex analysis allows us to understand and study elementary functions like polynomials, rational functions, exponential functions, trigonometric functions, and logarithmic functions. It provides insight into their properties and behavior in the complex plane. Analytic functions, which are infinitely differentiable, form the foundation of complex analysis and are employed in solving a wide range of mathematical problems.

2. Mapping and Transformations

Complex analysis helps in understanding the transformation of geometric shapes in the complex plane. Conformal mappings, a type of transformation that preserves angles, have applications in mathematical physics, image processing, and engineering. They play a significant role in solving problems related to fluid flow, heat transfer, and more.

3. Residue Theory and Complex Integration

Residue theory is a powerful tool in complex analysis that simplifies the evaluation of complex integrals. It allows us to calculate tricky contour integrals and solve seemingly impossible problems with great ease. This theory finds applications in various fields, including physics, engineering, and statistics.

4. Fractals and Chaos Theory

Complex analysis helps us understand intricate patterns found in fractals, which are complex geometric shapes that exhibit self-similarity at different scales. Fractals have applications in computer graphics, data compression, and modeling natural phenomena. Furthermore, complex analysis is also involved in the study of chaotic systems, where small changes in initial conditions can lead to significant variations in outcomes.

Complex analysis can be seen as an application of mathematical analysis to complex functions f(z) with variable z. The results obtained in the complex field have a lot of applications and are able to provide a deeper understanding of mathematics, also with regard to real functions, solving their intrinsic problems, such as the calculation of the square root of a negative number. The theory of complex analysis is more subtle than that dedicated to functions with two real variables, although a complex number has two degrees of freedom: its real part x and its imaginary part y, in the Cartesian representation z=x+iy. For example, the differentiability of a complex function requires additional conditions with respect to the simple existence and continuity of the partial derivatives with respect to the real and imaginary parts. In this theoretical text we expose the fundamental results representing the foundations of all the complex analysis. The general topics are: complex numbers and their properties, functions in the complex field, analytic functions and their singularities, integration and series in the complex field, Taylor series and Laurent series, residues and their calculation techniques, multivalued functions, dispersion relations, Euler's gamma function. Among the most important theorems and results we find: Cauchy's theorem, Cauchy's integral representation, Morera's theorem, residue theorem, Jordan's lemma, Schwarz's reflection principle, Mittag-Leffler expansion.
