Dear Participants,
We hope you are enjoying our series on Instanton Physics. As we approach Lecture 5, we would like to inform you that we will have an informal class discussion on Lectures 1-4 before proceeding further. This discussion will help reinforce key concepts and address any questions you may have.
Please note that due to some participants being away on 23rd June, Lecture 5 is now rescheduled for 30th June.
Thank you for your understanding and continued participation.
