# Module MA3422: Functional analysis II

**Credit weighting (ECTS)**- 5 credits
**Semester/term taught**- Hilary term 2012-13
**Contact Hours**- 11 weeks, 3 lectures including tutorials per week
**Lecturer**- Prof. Richard Timoney
**Learning Outcomes**-
On successful completion of this module, students will be able to:
- give the appropriate definitions, theorems and proofs concerning the syllabus topics, including topics related to weak toploogies, compactness, Hahn-Banach theorem, reflexivity, commutative Banach algebras;
- solve problems requiring manipulation or application of one or more of the concepts and results studied;
- formulate mathematical arguments in appropriately precise terms for the subject matter;
- apply their knowledge in mathematical domains where functional analytic techniques are relevant.

**Module Content**-
- Major theorems:
- Closed graph theorem, uniform boundedness principle, Hahn-Banach theorem.
- Dual spaces:
- Canonical isometric embedding in double dual, reflexivity, examples of reflexive and non-reflexive spaces.
- General topology:
- Product topology. Tychonoff theorem on compactness of (general) product space
- Weak and weak*-topologies:
- Compactness of the unit ball of the dual in the weak*-topology.
- Gelfand theory of commutative Banach algebras:
- Maximal ideal space. Gelfand transform.

**Module Prerequisite**- MA3421
**Assessment Detail**-
This module will be examined jointly with MA3421
in a 3-hour
**examination**in Trinity term, except that those taking just one of the two modules will have a 2 hour examination.**Continuous assessment**will contribute 15% to the final grade for the module at the annual examination session.
