MAS350 Measure and Probability
|Semester 2, 2017/18||10 Credits|
|Lecturer:||Prof David Applebaum||uses MOLE||Timetable||Reading List|
Measure theory is that branch of mathematics which evolves from the idea of "weighing" a set by attaching a non-negative number to it which signifies its worth. This generalises the usual physical ideas of length, area and mass as well as probability. It turns out (as we will see in the course) that these ideas are vital for developing the modern theory of integration.The module will give students an additional opportunity to develop skills in modern analysis as well as providing a rigorous foundation for probability theory. In particular it would form a useful precursor or companion course to the Level 4 courses MAS436 (Functional Analysis) and MAS452 (Stochastic Processes and Finance), the latter of which is fundamentally dependent on measure theoretic ideas.
Prerequisites: MAS211 (Advanced Calculus and Linear Algebra); MAS221 (Analysis)
