DESCRIPTION:Title: Virtual cactus group is virtually special compact\n\nAbs
 tract: The cactus group has been studied in various settings\, first appea
 ring as a 'mock reflection group'. Its “pure” subgroup is the fundamental 
 group of the iterative blowup of a hyperplane arrangement (the Deligne-Mum
 ford space). The virtual cactus group is a modified version of the cactus 
 group. In recent years\, techniques from geometric group theory were used 
 to determine properties of the cactus group. It was shown that the cactus 
 group is virtually special compact. In this talk\, we will present this vi
 ewpoint and prove that the virtual cactus group is also virtually special 
 compact.\n\nThere will be teatime in the lounge after the talk at 5pm.\n
