We prove that, after a suitable rescaling, the Selberg zeta functions converge to the Ihara zeta function of a limiting finite graph associated with the relevant non-Archimedean Schottky group acting on the Berkovich projective line. Moreover, our techniques can be used to obtain effective statements. One key idea is to introduce an intermediate zeta function that captures Archimedean and non-Archimedean information (while the Selberg resp. Ihara zeta function concerns only Archimedean resp. non-Archimedean properties).

The collaborative consists of four pillars: Kohn Professors, Kohn Scholars, policy impact and the Kohn Prize.\r\n\r\nThe Karl and Martha Kohn Professorship of Social Policy is intended to promote social equity through U.S. education policy, with a focus on childhood development.\r\n\r\nSpeaker Bio:\r\n\r\nChristina Weiland is the Karl and Martha Kohn Professor of Social Policy at the Ford School of Public Policy and Professor at the Marsal Family School of Education at the University of Michigan. She co-directs the Education Policy Initiative (with Dr. Kevin Stange) and directs the University of Michigan\u2019s Predoctoral Training Program in Causal Inference in Education Policy Research. She is also a Senior Research Fellow at the Learning Policy Institute and a Non-Resident Fellow at the Urban Institute.\r\n\r\nDr. Weiland\u2019s research focuses on the effects of early childhood interventions and public policies on children\u2019s development, especially on children from families with low incomes. She is particularly interested in the active ingredients that drive children\u2019s gains in successful, at-scale public preschool programs. She is also interested in quantitative research methods, educational measurement, and developmental processes research. Her work is also characterized by strong, long-standing research collaborations with practitioners, particularly the Boston Public Schools Department of Early Childhood.", "occurrence_notes":"Reception following event", "guid":"134659-21874771@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/134659", "building_id":"1005101", "building_name":"Weill Hall (Ford School)", "campus_maps_id":"527", "room":"1120", "location_name":"Weill Hall (Ford School)", "has_livestream":0, "cost":"", "tags":["Education","Faculty","ford school of public policy","lecture","policy talks @ the ford school","Public Policy","Sociology"], "website":"", "sponsors":[ { "group_name":"Gerald R.
