To all enthusiasts for higher structures and homotopical algebra, We are organizing a special session at the AMS Sectional Meeting at the University of Massachusetts in Amherst, MA. The dates of this meeting are October 1-2, 2022 (Saturday-Sunday), and we expect it to occur in-person. We would be delighted if you participated, and please feel free to encourage others to attend as well. Information about this meeting can be found at http://www.ams.org/meetings/sectional/sectional.html Special sessions follow some AMS policies that may not resemble other conferences you?ve attended, so bear in mind the following: 1) The AMS does not pay any expenses of faculty attending special sessions. However, PhD students are encouraged to apply for travel funding from AMS; see http://www.ams.org/student-travel for more information, including application procedures and deadlines. 2) Everyone who attends the meeting is required to pay a registration fee. Over the years there have been a significant proportion of meeting participants who have not done so, resulting in a considerable loss of revenue to the AMS. For information about the cost of registering, child care, or special needs, see https://www.ams.org/meetings/sectional/2301_other.html Best, John Berman, Michael Ching, Ivan Contreras Palacios, Owen Gwilliam, and Martina Rovelli [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
