Campus SNS
Programs PG
Session Fall Semester 2016
Course Title Functional Analysis
Course Code MATH-806
Credit Hours 3-0
Course Objectives This lecture course aims to introduce students to the basic concepts of Functional Analysis.

Brief Decommention of the Course:

Functional analysis plays an important role in the applied sciences as well as in mathematics itself. Roughly speaking, functional analysis develops the tools from calculus and linear algebra further to the more general setting where one has vector spaces comprising functions or general abstract infinite-dimensional vector spaces. Problems from various application areas can then be conveniently posed in this common general set up, and solved using the techniques of functional analysis. The basic objects studied in functional analysis are vector spaces with a notion of distance between vectors, and continuous maps between such vector spaces. This interplay between the algebraic and analytic setting gives rise to many interesting and useful results, which have a wide range of applicability to diverse mathematical problems.

Learning Outcomes:

On successful completion of this course, students will be able to
  • determine whether a mapping is a metric on a given set;
  • prove that a given metric space is complete;
  • determine whether a mapping is a norm on a vector space;
  • recognize whether a normed space is compact;
  • know basic properties of bounded and continuous linear operators on normed spaces;
  • know about the normed space of operators and dual spaces;
  • prove some results about Hilbert spaces;
  • recognize unitary, adjoint and normal operators on Hilber spaces;
  • represent functionals on Hilbert spaces;
  • know about Hahn-Banach theorem, open mapping theorem and closed graph theorem.
