Re: In Minkovsky space, is there an instanton solution for Yang-Mills (or self-dual Yang-Mills) field Eq

[Jack Uretsky <jlu@HEP.ANL.GOV>]

Hi-
        I don't quite understand the question, and I'm not an expert BUT
"instanton" is defined only in Euclidean space.  In Yang-Mills you can
have an instanton if the time components of the potentials vanish, but
this would not seem to be a gauge-invariant quantity.  See Weinberg's
books, chap 23.
                                Regards,
                                        Jack

Adam was by constitution and proclivity a scientist; I was the same, and
we loved to call ourselves by that great name...Our first memorable
scientific discovery was the law that water and like fluids run downhill,
not up.
