MATH3979课程简介
This unit continues the study of functions of a complex variable introduced in the second year unit Analysis (MATH2023/2923). It is aimed at highlighting certain topics from analytic function theory that have wide applications and intrinsic beauty. By learning about the analysis of functions of a complex variable, you will acquire a very important background for mathematical areas such as dynamics, algebraic and differential geometry, and number theory; and advanced theoretical physics such as quantum mechanics, string theory, and quantum field theory. The unit will begin with a revision of properties of complex numbers and complex functions. This will be followed by material on conformal mappings, Riemann surfaces, complex integration, entire and analytic functions, the Riemann mapping theorem, analytic continuation, and Gamma and Zeta functions. Finally, special topics chosen by the lecturer will be presented, which may include elliptic functions, normal families, Julia sets, functions of several complex variables, or complex manifolds. At the end of this unit you will have received a broad introduction and gained a variety of tools to apply them within your further mathematical studies and/or in other disciplines.
Prerequisites
At the completion of this unit, you should be able to:
- LO1. demonstrate a conceptual understanding of limit, continuity, differentiation, and integration as well as a thorough background in variety of techniques and applications of complex analysis
- LO2. assess problems in the framework of complex analysis, to choose among several potentially appropriate mathematical methods of solution, and persist in the face of difficulty
- LO3. present complete and mathematically rigorous solutions for problems in complex analysis that include appropriate justification for their reasoning
- LO4. recognise problems in mathematics, science, engineering and real life that are amenable to complex analysis, and to formulate models for such problems and apply the techniques of complex analysis in solving them

Let $z_0 \in \mathbb{C}$ and $a, b \in \mathbb{R}$ be arbitrary. Draw the set consisting of all $z \in \mathbb{C}$ satisfying the following conditions. In each case, state whether the set is open, closed, or neither.
(i) $1<|z|<2$ (ii) re $z \geq 0$ and im $z \leq$ re $z$ (iii) re $z \geq 0$ and $1<|z|<2$ (iv) $\mathrm{re}\left(z z_0\right)>0$
(v) $a<\arg \left(z-z_0\right)0$
(x) $\operatorname{re}\left(z^2\right) \leq 0$
(xi) $\operatorname{re}\left(z^2\right)>1$
(xii) $\operatorname{re}\left(z^2\right) \leq 1$
Find the following limits, if they exist. If they do not exist, explain why.
(i) $\lim {z \rightarrow 0}|z| / z$ (ii) $\lim {z \rightarrow 0}|z|^2 / z$
(iii) $\lim {z \rightarrow 0} z /|z|^2$ (iv) $\lim {z \rightarrow 0}(z-$ re $z) / \operatorname{im} z$
Prove from first principles that the following functions are continuous:
(i) $\mathrm{re} z$
(ii) $\mathrm{im} z$
(iii) $z+|z|$
(iv) $1 / z(z \neq 0)$
(v) $|z|^2$
For each of the following sets and pairs of points, define (if possible) (a) a path in the set between the two points, and (b) a step path in the set between the two points.
(i) $|z|<2 ; 1+\mathrm{i}, 1-\mathrm{i}$ (ii) $|z|=1 ;-\mathrm{i}$, i (iii) $1 \leq|z| \leq 2 ; \sqrt{2},-\sqrt{2}$ (iv) $\mid$ re $z \mid>5 ;-9+37 \mathrm{i}, 1066+\mathrm{i}(\pi+\sqrt{5} / 17)$
(v) $|1-| z||>\frac{1}{2} ; \mathrm{i} / 3,49(1+\mathrm{i})$
Let $S$ be a subset of $\mathbb{C}$. If $z, w \in S$, define $z \sim w$ if and only if there is a path from $z$ to $w$. Show that $\sim$ is an equivalence relation. The equivalence classes are components of $S$. If $S$ is open and non-empty, show that each component is a domain.
