I will discuss a dynamical decomposition of automorphisms t hat produces a canonical decomposition of the corresponding free-by-cyclic groups. This will involve the partial order on attracting laminations for an automorphism. The decomposition of free-by-cyclic groups can be consid ered an extension of the JSJ decomposition of 3-manifolds. This talk is on joint work with Spencer Dowdall\, Yassine Geurch\, Radhika Gupta\, and Ca glar Uyanik.\n\nWe will gather in the lounge for teatime after the talk. T his will be our last seminar of the semester.\n DTSTART:20260408T200000Z DTEND:20260408T210000Z LOCATION:Room 1104\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Jean Pierre Mutanguha (º£½ÇÉçÇø) URL:/mathstat/channels/event/jean-pierre-mutanguha-mcg ill-university-372288 END:VEVENT END:VCALENDAR
