    The probability that xmx^m and yny^n commute in a compact group

    In a recent article [K.H. Hofmann and F.G. Russo, The probability that xx and yy commute in a compact group, Math. Proc. Cambridge Phil. Soc., to appear] we calculated for a compact group GG the probability d(G)d(G) that two randomly picked elements x,yGx, y\in G satisfy xy=yxxy=yx, and we discussed the remarkable consequences on the structure of GG which follow from the assumption that d(G)d(G) is positive. In this note we consider two natural numbers mm and nn and the probabilty dm,n(G)d_{m,n}(G) that for two randomly selected elements x,yGx, y\in G the relation xmyn=ynxmx^my^n=y^nx^m holds. The situation is more complicated whenever n,m>1n,m>1. If GG is a compact Lie group and if its identity component G0G_0 is abelian, then it follows readily that dm,n(G)d_{m,n}(G) is positive. We show here that the following condition suffices for the converse to hold in an arbitrary compact group GG: ``For any nonopen closed subgroup HH of GG, the sets {gG:gkH}\{g\in G: g^k\in H\} for both k=mk=m and k=nk=n have Haar measure 00''. Indeed we show that if a compact group GG satisfies this condition and if dm,n(G)>0d_{m,n}(G)>0, then the identity component of GG is abelian

    SU(2,CMB), the nature of light and acceleratedcosmological expansion

    No full text
    We present quantitative and qualitative arguments in favor of the claim that, within the present cosmological epoch, the U(1)gamma factor in the Standard Model is an effective manifestation of SU(2) pure gauge dynamics of Yang-Mills scale Lambda ~ 10^-4 eV. Results for the pressure and the energy density in the deconfining phase of this theory, obtained in a nonperturbative and analytical way, support this connection in view of large-angle features inherent in the map of the CMB temperature fluctuations and temperature-polarization cross correlations
