### Learning Outcomes

On successful completion of this module students should be able to:

Identify the properties of complex functions and describe their effects on objects in the complex plane.

Understan the effect of a range of mapping including the exponential, cosine multifunctions and logarithmic functions.

Demonstrate a broad understanding of the properties of Mobius transformations and their applications.

Understand the process of stereographic projection.

### Brief description

This course aims to develop the student's grasp of the geometric signficiance of complex transformations and their mapping properties. Students will solve problems with a number of transformations, including Mobius transformations and stereographic projections, which are important in a number of contemporary contexts.

### Content

Geometry of complex arithmetic: Euler's theorem revisited, applications, Euclidean geometry.

Complex functions as transformations: the exponential function, the cosine and sine functions, multifunctions and logarithmic functions.

Mobius transformations: Inversion, the Riemann sphere, sterographic projection, Mobius transformations, visualistion and classification, decomposition, automorphism.

The geometry of complex differentiation: Local description of mapps, conformality, physical applications.
