Attendance and activity in the weekly teaching sessions (40%), submitted weekly homework problems (40%), and submitted pre-session exercise problems (20%). For details on the topics and grading, see the course Moodle page.


The student is introduced to advanced techniques in linear operator theory and fundamental results in infinite-dimensional normed linear spaces. The main focus is in the theory of closed operators. The results and techniques are linked to the analysis of linear partial differential equations. In addition, the student will learn advanced proof techniques in functional analysis. After the course the student will be able to employ abstract operator techniques and the theory of Sobolev spaces in studying the existence and regularity of solutions of linear elliptic partial differential equations.
