### Analytic combinatorics (NDMI087)

The lecture will take place on Monday at 9am in the room S8. The
exercises will take place on Tuesdays at 9am in S321 (third floor
corridor). Homework will be avalable as a substitute for those who
cannot attend the exercises. Note that the exercise session is once
every fortniight, starting on March 7. The course will be in English.

Brief synopsis: power series, ordinary and exponential generating
functions, basics of complex analysis, application of complex-analytic
tools in combinatorics. No prior knowledge of complex analysis is
needed. Some prior familiarity with generating functions, e.g. from the
basic course in Combinatorics and graphs, may be beneficial.
