We propose\nan entropic variant of Korpelevich\u2019s extragradient algorithm\u2014the Kullback\u2013Leibler Mirror-Prox\nmethod\u2014in which Euclidean projections are replaced by relative-entropy proximal steps. Each\nhalf-step is therefore an explicit exponential reweighting of the current measure, implemented on a\nfinite state-space discretization. Under Lasry\u2013Lions monotonicity and continuity assumptions, we\nprove convergence of mesh-refined ergodic averages and obtain finite-iteration Minty-residual and\napproximate-equilibrium bounds that jointly quantify iteration and discretization errors. Under\nstrong monotonicity, we derive metric convergence rates for the last, best, and averaged iterates.\nWe also develop a KL-type Tikhonov regularization that selects the equilibrium minimizing relative\nentropy with respect to a reference measure. The framework applies to potential and nonpotential\ncost operators and does not require differentiability or convexity of the cost in the individual state.\n\nJoint work with Erhan Bayraktar, Ibrahim Ekren and Lu Vy.", "occurrence_notes":null, "guid":"150040-21907900@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/150040", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"1360", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Financial\/Actuarial Mathematics Seminar - Department of Mathematics", "group_id":"4890", "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":21907900 } , "112678-21913936": { "datetime_modified":"20260921T144026", "datetime_start":"20261014T160000", "datetime_end":"20261014T170000", "has_end_time":1, "date_start":"2026-10-14", "date_end":"2026-10-14", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"Pizza with Professors: Program in Biology", "occurrence_title":"", "combined_title":"Pizza with Professors: Program in Biology", "event_subtitle":"", "event_type":"Social \/ Informal Gathering", "event_type_id":"19", "description":"Join us for an informal meeting to eat and network with faculty!
