SUMMARY:Atlantic Graph Theory Seminar
DESCRIPTION:On the two table case of the directed Oberwolfach problem\nSpeaker: Alice Lacaze-Masmonteil\, University of Regina\n\nA directed variant of the famous Oberwolfach problem\, the directed Oberwolfach problem considers\nthe following scenario. Given n people seated at t round tables of size m1\,m2 . . . \,mt \, respectively\,\nsuch that m1+m2+· · ·+mt = n\, does there exist a set of n−1 seating arrangements such\nthat each person is seated to the right of every other person precisely once? I will first demonstrate\nhow this problem can be formulated as a type of graph-theoretic problem known as a cycle decomposition\nproblem. Then\, I will discuss a particular style of construction that was first introduced\nby R. Häggkvist in 1985 to solve several cases of the original Oberwolfach problem. Lastly\, I will\nshow how this approach can be adapted to the directed Oberwolfach problem\, thereby allowing\nus to obtain solutions for previously open cases. Certain results discussed in this talk arose from\ncollaboration with Daniel Horsley.\n\nZoom link:\nhttps://us02web.zoom.us/j/86861499971?pwd=rTDAaju0TCu24asnaBGvkuNlT11KZ1.1\n\nMeeting ID: 868 6149 9971\nPasscode: 325258
