000091307 245 1_ $a Thompson’s group is the orientation-preserving automorphism group of a cellular complex
000091307 520 3_ $a We consider a planar surface ∑ of in nite type which has Thompson's group T as asymptotic mapping class group. We construct the asymptotic pants complex C of ∑ and prove that the group T acts transitively by automorphisms on it. Finally, we establish that the automorphism group of the complex C is an extension of the Thompson group T by Z=2Z.
