C* algebras and spectral theorem

By Prof. E. K. Narayanan | IISc Bangalore

Learners enrolled: 437

ABOUT THE COURSE:
Aim is to prove the spectral theorem for bounded normal operators using C* algebras and projection valued measures. After review of spectral theorem for compact normal operators we will introduce Banach algebras, C* algebras and prove Gelfand-Naimark theorem. Spectral theorem will be proved after a detailed study of projection valued measures and their properties

INTENDED AUDIENCE: MSc 2nd year , PhD students and college lecturers

PREREQUISITES: First course in functional analysis is a must. See http://math.iisc.ac.in/all-courses/ma223.html
