Clavius Community Notes
2019 Holy Cross, Worcester,
Massachusetts
Meeting #57: 22 June to 6 July
At the invitation of the College of the Holy Cross and its Department of Mathematics and Computer Science, the Clavius group gathered at Holy Cross for its fifty-seventh session. We were provided with office space in Swords Hall and a lecture room in Smith Labs for our seminars and talks. Also, access to photocopying, printing services, email and the web was provided. The group’s housing arrangements and other needs were generously attended to by Chip O’Connor, Director of Conference Services at Holy Cross. Members were housed in the Figge apartment complex, an excellent arrangement that made it possible for us to continue our vibrant community life. As is customary, each day was concluded by Mass and a community meal. The participants this summer consisted of five Jesuits, one Salvatorian sister, six married couples and four single lay persons. Fifteen Clavius mathematicians participated in the lectures and seminars along with several faculty members from Holy Cross and other colleges and universities.
