Chapter 427: All Regretful?

"Professor Witten, could you explain the integration invariance under different metrics g in the mathematical intertwining formula I(ϕ) of Q theory? Specifically, if we integrate under Riemannian and pseudo-Riemannian metrics, should the results be the same? If they differ, how do you maintain theoretical consistency?"

From the podium, Edward Witten, who had just finished his presentation, looked at Critiel Matich with a slight headache.

During the Q&A session, when he saw Matich raise his hand to ask a question, he signaled the host to call on him. After all, they were old rivals, and it felt incomplete not to have a little verbal spar.

But now he even thought to himself that he should not have sent an invitation to this stubborn guy. As expected, this guy was always thinking about how to play the opposite. Looking for loopholes in the theory he supported.
