square173205 Posted November 29, 2007 Share Posted November 29, 2007 The ultraviolet divergence in QED is an old problem. The renormalisation removes almost every divergence appeared in the perturbation calculations, however the divergent integral before renormalisation should be finite if the physical model is correct. This might imply it is necessary to quantise special relativity itself, for as long as concerning point-like particle in Lorentz space the above problem seems not to be mended. I tried to quantise Lorentz space in order to deal with the ultraviolet divergence in the following site; http://hecoaustralia.fortunecity.com/relativity/relativity3.htm Link to comment Share on other sites More sharing options...
ajb Posted November 29, 2007 Share Posted November 29, 2007 You should look up noncommutative geometry, the Moyle plain and deformation quantisation. There are many papers on quantum field theory on a noncommutative spacetime in various contexts. Link to comment Share on other sites More sharing options...

Martin Posted November 30, 2007 Share Posted November 30, 2007 Yes, thank you for the correction. You are most welcome, ajb. Anyone who's Jewish or has lots of Jewish friends will recognize Mo'el (pronounced moyl) as the name of a profession. the Moyl is the guy who performs ritual circumcisions Link to comment Share on other sites More sharing options...
