Prerequisites: MATH1022 (Introductory Group Theory) AND
either MATH1035 (Analysis) or MATH1050 (Calculus and Mathematical Analysis)
Please see me if are an Erasmus student, or you have not got these prerequisites for some other reason.
Module details: 2011--12
Lecturer: Prof. J.C. Wood, 8.20e, Mathematics;
Module home page:
which should also be accessible from Blackboard - VLE:
Mondays: 0900--1000, Roger Stevens LT 3
Wednesdays: 1200--1300, Roger Stevens LT 16
Thursdays: 1600--1700, Roger Stevens LT 16
Five of these sessions will be workshops.
If you want help, please come and see me: fix a time when you see me at lectures or by e-mail.
Attendance monitoring From the School of Mathmematics webpages:
http://www.maths.leeds.ac.uk/school/students/Student_Attendance.html where you can find more details:
`Students are expected to attend all teaching activities, including examples classes.
Attendance at lectures will be monitored on several randomly chosen ocassions chosen by the administrative staff.

Assessment: 100% examination (2.5 hours long) at end of semester.
Private Study: There are 33 hours of lectures; about 5 of these will be Examples Classes. There are 117 hours of private study, so you should expect to spend about 10 hours a week on private study for this module.
