Frasca's mapping of classical Yang-Mills to $\phi^4$ theory

Question

I recently came across an article on the arXiv 0709.2042 written by Marco Frasca, where he provides a mapping between classical Yang-Mills theory to $\phi^4$ theory. Has his idea been fruitful in understanding the infrared regime of quantum Yang-Mills theory, as he claims?

Answer 1

A mathematician named Terry who specializes in analysis argued rather convincing here that the main theorem in Frasca's paper is incorrect.
