Résume
It is well known that the absolute Galois group ofthe rational number field is embedded in theGrothendieck-Teichmueller group GT.The main parameter of GT is valued in the free profinitegroup of two variables. We specialize these variablesto certain 2 by 2 matrices, and find the parameterimages closely related with Anderson-Ihara's adelicbeta functions.
