Abstract. We study the sineGordon model in two dimensional space time in two
different domains. For
beta > 8 pi and weak coupling, we introduce an ultraviolet cutoff and
study the infrared
behavior. A renormalization group analysis shows that the the model is
asymptotically free
in the infrared. For beta < 8 pi and weak coupling, we introduce an
infrared cutoff and
study the ultraviolet behavior. A renormalization group analysis shows
that the model is
asymptotically free in the ultraviolet.
