Indeed, just as M_{1,1} = A_1 is the quotient H\/SL_2(Z), one can show that A_g, the space of principally polarized abelian varieties of dimension g, is isomorphic to H_g\/Sp_{2g}(Z). More generally, one can consider spaces H_g\/Gamma for any arithmetic subgroup Gamma in Sp_{2g}(Q). Unlike M_g, which admits the canonical Deligne-Mumford compactification, these spaces admit many natural compactifications with different geometric properties. In this talk, we introduce H_g\/Gamma, the Siegel modular varieties, and discuss various compactifications such as the Baily\u2013Borel compactification and toroidal compactifications. We then focus on the specific case of g = 2 to showcase the beautiful arithmetic that occurs even in this small case.", "occurrence_notes":null, "guid":"154655-21918147@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/154655", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"2866", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Student Algebraic Geometry Seminar - Department of Mathematics", "group_id":"4904", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21918147 } , "138091-21908267": { "datetime_modified":"20260812T103351", "datetime_start":"20261113T150000", "datetime_end":"20261113T160000", "has_end_time":1, "date_start":"2026-11-13", "date_end":"2026-11-13", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Sustainability Coffee Chats: Free coffee and good conversation!", "occurrence_title":"", "combined_title":"Sustainability Coffee Chats: Free coffee and good conversation!", "event_subtitle":"", "event_type":"Social \/ Informal Gathering", "event_type_id":"19", "description":"The Student Sustainability Coalition will be hosting our coffee chats throughout the semester and we want you to join us!

Many of these priests are from India and they come on the R-1 temporary religious worker visa - a lesser researched visa category in South Asian diaspora studies that does not require a salary, only compensation. Thomas' research shows that 64%+ of missionary priests from India come from dominant caste backgrounds. Based on chapters from my forthcoming book on Indian Catholic priests in Eastern Montana and Western North Dakota, in this talk I discuss caste, remittances, and the intricacies of the R-1 religious worker visa. \n\nSonja Thomas is a professor of women\u2019s gender and sexuality studies at Colby College. Her research focuses on gender, race, caste, and Christianity in India and the U.S. She is the author of *Privileged Minorities: Syrian Christianity, Gender, and Minority Rights in Postcolonial India*. Her second book, *Indians and Cowboys, on Catholic priests from India in rural America*, is forthcoming from University of Washington Press. She is an associate editor of *South Asia: The Journal of South Asian Studies*, is a member of Waterville Maine's K-12 Social Justice and Equity group, and is an appointed commissioner with Maine\u2019s Permanent Commission on Racial, Indigenous, and Tribal Populations.\n\nIf there is anything we can do to make this event accessible to you, please contact us.
