Introduction to differential forms, spring 2011
Differential forms give a coordinate free formalism for multivariable calculus and a point of view to modern analysis. This formalism can also be used
to understand basic concepts in algebraic topology as homology and cohomology. In this course we discuss how familiar methods from calculus give rise
to more abstract concepts in topology.
Background in algebraic topology or in differential geometry is not necessary.
Real analysis and Topology II (or equivalent).
Weeks 3-9 and 11-18, Tuesday 16-18 and Thursday 10-12 in room B321. (Note: Change in Tuesdays lecture time.)
Easter holiday 21.-27.4.
Methods of passing the course
The course can be passed by returning written solutions to weekly problem sets. Solutions are graded with scale 0-6. Problems discussed in the exercise sessions give extra credit. Course can be also passed by an exam. Contact the lecturer for details.
