  Yang-Mills theory in the Minkowski plane

+ 2 like - 0 dislike
486 views

It is well-known that quantum Yang-Mills theory in the cylinder is exactly solvable. But what happens for Yang-Mills in the 2D Minkowski plane? There should be something like a limit where the radius goes to infinity but I have never seen this discussed. Are there papers discussing this limit? If not, what is the reason?

asked Dec 31, 2016 in Theoretical Physics by Arnold Neumaier (15,787 points) [ revision history ]

The difference may be in the boundary conditions. Whether there are the reflected waves or  the outgoing waves are absorbed; that is what makes a difference, in my humble opinion.
