Talagrand also suggested a discrete version of the Convexity Conjecture and called it \u0022my lifetime favorite problem,\u0022 offering $1,000 prize for its solution. We introduce a reformulation of the discrete Convexity Conjecture using the new notion of \u0022k-thresholds,\u0022 which is an extension of the traditional notion of thresholds, introduced by Talagrand. Some ongoing work on understanding k-thresholds, along with a (vague) connection between the Kahn-Kalai Conjecture and the discrete Convexity Conjecture, will also be discussed. Joint work with Michel Talagrand.\u003C\/p\u003E\u003Cp\u003E\u003Cbr\u003E\u003Cem\u003EPhoto by Rod Searcey\u003C\/em\u003E\u003Cbr\u003E\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E\u003Ch5\u003EAbout the Speaker\u003C\/h5\u003E\u003Cp\u003EJinyoung Park is an Assistant Professor of Mathematics at the Courant Institute, NYU. Her research interests include extremal and probabilistic combinatorics. She earned her Ph.D. in mathematics from Rutgers University in 2020, under the supervision of Jeff Kahn. Following her Ph.D., she was a postdoctoral researcher at the Institute for Advanced Study (IAS) and Stanford University before joining the faculty of the Courant Institute at NYU in 2023. Park received her bachelor\u0027s degree in mathematics education from Seoul National University in 2005 and worked as a secondary school mathematics teacher until 2011. She has received several honors and awards, including the AMS Conant Prize, the D\u00e9nes K\u00f6nig Prize, and the Maryam Mirzakhani New Frontiers Prize.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cdiv\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cp\u003EJinyoung Park, an Assistant Professor of Mathematics at the Courant Institute, will give the Atlanta Combinatorics Colloquium talk on The Convexity Conjecture, the Kahn-Kalai Conjecture, and an introduction to k-thresholds.\u003C\/p\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cdiv\u003E\u003Cdiv\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cp\u003E\u003Cbr\u003E\u0026nbsp;\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Jinyoung Park, an Assistant Professor of Mathematics at the Courant Institute, will give the Atlanta Combinatorics Colloquium talk on The Convexity Conjecture, the Kahn-Kalai Conjecture, and an introduction to k-thresholds."}],"uid":"34518","created_gmt":"2025-10-10 21:18:29","changed_gmt":"2025-10-11 15:24:37","author":"sbarone7","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-10-30T16:30:00-04:00","event_time_end":"2025-10-30T17:30:00-04:00","event_time_end_last":"2025-10-30T17:30:00-04:00","gmt_time_start":"2025-10-30 20:30:00","gmt_time_end":"2025-10-30 21:30:00","gmt_time_end_last":"2025-10-30 21:30:00","rrule":null,"timezone":"America\/New_York"},"location":"Skiles 006","extras":["free_food"],"hg_media":{"678336":{"id":"678336","type":"image","title":"Headshot of Jinyoung Park - Photo by Rod Searcey","body":"\u003Cp\u003EHeadshot of Jinyoung Park - Photo by Rod Searcey\u003C\/p\u003E","created":"1760136796","gmt_created":"2025-10-10 22:53:16","changed":"1760136796","gmt_changed":"2025-10-10 22:53:16","alt":"Headshot of Jinyoung Park - Photo by Rod Searcey","file":{"fid":"262352","name":"headshot_Park_Photo.jpg","image_path":"\/sites\/default\/files\/2025\/10\/10\/headshot_Park_Photo.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/2025\/10\/10\/headshot_Park_Photo.jpg","mime":"image\/jpeg","size":145188,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/2025\/10\/10\/headshot_Park_Photo.jpg?itok=WJv5a6GX"}},"678335":{"id":"678335","type":"image","title":"Jinyoung Park - Photo by Rod Searcey","body":"\u003Cp\u003ESlide for Jinyoung Park - Photo by Rod Searcey\u003C\/p\u003E","created":"1760136749","gmt_created":"2025-10-10 22:52:29","changed":"1760136749","gmt_changed":"2025-10-10 22:52:29","alt":"Jinyoung Park - Photo by Rod Searcey","file":{"fid":"262351","name":"slide_park_11x14b.png","image_path":"\/sites\/default\/files\/2025\/10\/10\/slide_park_11x14b.png","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/2025\/10\/10\/slide_park_11x14b.png","mime":"image\/png","size":109598,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/2025\/10\/10\/slide_park_11x14b.png?itok=K4j4jSZx"}},"678337":{"id":"678337","type":"image","title":"Poster of Jinyoung Park - Photo by Rod Searcey","body":"\u003Cp\u003EPoster of Jinyoung Park - Photo by Rod Searcey\u003C\/p\u003E","created":"1760136818","gmt_created":"2025-10-10 22:53:38","changed":"1760136818","gmt_changed":"2025-10-10 22:53:38","alt":"Poster of Jinyoung Park - Photo by Rod Searcey","file":{"fid":"262353","name":"poster_park_11x14b.png","image_path":"\/sites\/default\/files\/2025\/10\/10\/poster_park_11x14b.png","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/2025\/10\/10\/poster_park_11x14b.png","mime":"image\/png","size":196622,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/2025\/10\/10\/poster_park_11x14b.png?itok=LjPBaDCt"}}},"media_ids":["678336","678335","678337"],"groups":[{"id":"1279","name":"School of Mathematics"}],"categories":[],"keywords":[{"id":"193733","name":"_for_math_site_manual_feed_"},{"id":"173647","name":"_for_math_site_"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Ca href=\u0022mailto:comm@math.gatech.edu\u0022\u003ESal Barone\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
