MONOPOLES NEAR THE PLANCK SCALE AND UNIFICATION
MONOPOLES NEAR THE PLANCK SCALE AND UNIFICATION
Considering our (3+1)-dimensional space-time as, in some way, discrete or l attice with a parameter $a=\lambda_P$, where $\lambda_P$ is the Planck length, we have investigated the additional contributions of lattice artifact monopoles to beta-functions of the renormalisation group equations for the running fine structure constants $\alpha_i(\mu)$ (i=1,2,3 correspond to the …
