In joint wo rk with them (arXiv:1704.05069)\, we arrived at a simpler definition of th e amplituhedron\, which I will present. One of the features of this defini tion is that the expected factorization when approaching boundaries is exp licitly visible. I will focus on this aspect.  \n DTSTART:20171121T203000Z DTEND:20171121T213000Z LOCATION:Room 4336\, CA\, Pav.
