SUBJECT
| MMA1001 | Special Topics in Functional Analysis |
| Teaching Staff in Charge |
Prof. BRECKNER Wolfgang, Ph.D., breckner math.ubbcluj.ro |
| Aims |
|
The aim is to deepen the students’ knowledge of functional analysis acquired during the undergraduate studies. There will be presented subjects concerning the fundamental algebraic-topological structures of functional analysis: topological linear spaces and locally convex spaces. |
| Content |
|
1. Elements of linear space theory: balanced sets, convex sets, maximal linear subspaces, hyperplanes
2. Linear topologies: neighbourhood bases, operators between topological linear spaces, continuity of linear functionals, separation of convex subsets of a topological linear space by a closed hyperplane 3. Locally convex topologies: characterizations of locally convex spaces, separation of convex subsets of a locally convex space by a closed hyperplane, extremal sets, extreme points 4. Linear spaces in duality: polars, the bipolar theorem, the duality pair generated by a separated locally convex space, weak topologies, the closed range theorem |

| Assessment |
|
The students’ knowledge will be assessed through two compulsory written tests: one examination in the seventh week of the semester, for the subjects studied during the first 6 weeks, and the following examination within the period of the exams session, for the subjects studied during the weeks 7 to 14. The final grade will be the arithmetic mean of the obtained grades, rounded if this mean is not an integer. The students willing to improve this grade and those absent from both written tests could take a single written examination for the entire course, during the re-examination session.
