Prerequisites


A working knowledge of functional analysis and operator theory, as well as some topology, as provided in, for example, MAGIC061. We lightly skirt over some of this material in the first couple of lectures.

Note:

Clicking on the link for a book will take you to the relevant Google Book Search page. You may be able to preview the book there. On the right hand side you will see links to places where you can buy the book. There is also link marked 'Find this book in a library'. This sometimes works well, but not always. (You will need to enter your location, but it will be saved after you do that for the first time.)

Assessment


Throughout the lectures you will find s in the margins. These indicate material that has been stated without justification. You are asked to fill in the details on as many of these as you can. The material will be collected at the end of the semester, and you are asked to provide your work in electronic form as a pdf file, preferably produced from a TeX source file.
