**MTH-382 Special Topic: Complex Variables**

The square root of -1, often denoted as i, is an interesting number. It is called, perhaps derisively, an “imaginary number,” and yet its presence leads to many mathematically beautiful results (arguably more beautiful and natural than their real counterparts). In this course, we will explore the algebraic properties of so-called complex numbers (i.e. numbers of the form x + iy where x and y are real numbers), differentiable functions of a complex variable and their properties, extensions of exponential and trigonometric functions to the complex variable and the relationships between such functions, and some classic results such as the maximum-modulus principle, Liouville’s Theorem, residue calculus, and the Fundamental Theorem of Algebra.
