Material
The course will follow the lecture notes "Funktonaalianalyysin peruskurssi" (2012, last updated in 2017) by Kari Astala, Petteri Piiroinen & Hans-Olav Tylli. Minor updates are possible also during the course and the most current version for the Autumn 2018 course can be downloaded from below.
* The notes are available only in Finnish but an English textbook substitute, which is particularly suitable for those who wish to focus on applications, is
Erwin Kreyszig: Introductory functional analysis with applications (Wiley, 1989)
* Although perhaps not optimal as a textbook, a concise but solid reference book including also material for the courses Real Analysis I and Complex Analysis I is
W. Rudin: Real and Complex Analysis (Tata McGraw-Hill) [chapters 3-5 summarize the main material for this course]
* The following books contain related material (as well as much more), and may be used as supplement to the course notes/textbook:
Bollobas: Linear Analysis (Cambridge Mathematical Textbooks)
Werner: Funktionalanalysis (Springer-Lehrbuch) [in German]
W. Rudin: Functional Analysis (McGraw-Hill) [Part I generalizes the theory to topological vector spaces]

Tasks
Homework sets, second period
The exercise sessions will be on Thursdays 14:15-16:00 in Exactum, C129, on the date marked at the top of the exercise sheet. You can either come to present your solutions in the session, or contact the instructor Kalle Koskinen (kalle.koskinen@helsinki.fi) to make alternative arrangements if you cannot attend it.
Please make free use of the Ratkomo -tutorial sessions on the 3rd floor: the schedule is available at the web page https://blogs.helsinki.fi/ratkomo-solvery/aikataulu-timetable/ As mentioned during the lectures, the lecturer and/or instructor are often also answering questions in Ratkomo on Tuesdays between 13-15. In particular, you are welcome to ask questions from the lecturer during the office hours on Tue 14-15 at Exactum D335.
