SUMMARY:Workshop / Seminar:Algebraic Geometry Seminar: Group actions on families of K3 categories
DESCRIPTION:There is a well-known obstruction distinguishing an action of a finite group G on a derived category from a mere identification of G with a subgroup of the group of autoequivalences. I will first explain how to extend this distinction to a family of categories and\, in the case of K3 surfaces\, how to use stability conditions to completely control this construction. \n\nAs one example\, this leads to a construction of non-commutative abelian surfaces (categories deformation-equivalent to derived categories of abelian surfaces) in exactly as much generality as one could reasonably hope for. The applications include the construction of every polarised Hyperkaehler variety of Kummer type from a moduli space.\n\nThis is based on joint work with Alex Perry\, Laura Pertusi and Xiaolei Zhao.

SUMMARY:Lecture / Discussion:Nibi Anishinaabe Ikwewag Inaakonigewin
DESCRIPTION:For generations\, Anishnaabe Ikwewag (women) have carried a special responsibility to nibi (water)\, the giver of life and a connection among people\, community\, and the natural world. Join indigenous women from across the Great Lakes to explore this sacred relationship\, the legacy of Nokimis Josephine Mandamin-ba and the water walkers\, and the future of women-led water protection and stewardship. \n\nPanelists:\nMyrna Kicknosway\, Elder\, Faculty of Law\, University of Windsor | Walpole Island First Nation\nAndrea Pierce\, Deputy Director of Programming\, Michigan Environmental Justice Coalition and Chair\, Anishinaabek Caucus | Little Traverse Bay Bands of Odawa Indians\nDawn Martin Hill\, Grandmother of 10\, resides in Six Nations of the Grand River with her four children | Mohawk Wolf Clan\nJudy Da Silva\, Elder\, Award-Winning Activist\, Community Leader | Grassy Narrows First Nation\n\nThis event is hosted by the Great Lakes Fishery Commission\, the Global Center for Transboundary Waters\, the Tishman Center for Social Justice and the Environment\, and the Water Center. Refreshments will be served.
