International Workshop on Operator Theory and its Applications

Monday 16th - Friday 20th August 2021

The International Workshop on Operator Theory and its Applications meets annually to bring together mathematicians and engineers who work in functional analysis and its application to related areas.

This meeting will feature plenary lectures by established experts, and workshop sessions for emerging areas of research. Early career researchers are welcome to participate. To discuss the scientific programme, please email Gordon Blower (
