Week 1
Welcome!
Convenor: Juan Carlos Ponce Campuzano
The point of this (and any) course is
to know more than when you started ...
1. Complex Numbers
2. Complex Functions
$f(z) = u(x,y) + i v(x,y)$
3. Differentiation
4. Integration
$ \ds \int_C f(z)\,dz = \int_a^bf\left(z(t)\right)z'(t)\,dt$
5. Complex Series
$ \ds \sum_{n=1}^{\infty}z_n=z_1+z_2+z_3+\cdots$
6. Residues (integration revisited)
$ \ds \int_C f(z)\,dz =2\pi i \sum_{z_k\text{ inside }C}\text{Res}_{z=z_k}f(z)$
7. Applications: Real integrals
$ \ds \int_{0}^{\infty}\frac{\sin x}{x}dx$
8. Applications: Inverse Laplace problems
|
$ \ds \mathcal{L}\left\{f\right\}=F(x) =\int_0^{\infty} e^{-st}f(t)\,dt$ |
|
9. Applications: Laplace's equation
$ \ds \nabla ^2 \phi(x,y)=0$
10. Applications: Series, Number Theory, Geometry, etc.
