%0 Journal Article %T Evidence for Large N Phase Transition in N=4 Super Yang-Mills Theory at Finite Temperature %A Miao Li %J Physics %D 1998 %I arXiv %R 10.1088/1126-6708/1999/03/004 %X The AdS/CFT correspondence provides valuable constraints on the possible exact form of various physical quantities in the ${\cal N}=4$ super Yang-Mills theory in the large N limit. We examine the free energy as the expansions in a small as well as in a large 't Hooft parameter $\lambda$. We argue that it is impossible to smoothly extrapolate from the weak coupling regime to the strong coupling regime, thus there must exist a large N phase transition in $\lambda$ at a finite temperature. We also argue that there is no world-sheet instanton in the background of the Euclidean anti-de Sitter black hole. %U http://arxiv.org/abs/hep-th/9807196v2
