SUMMARY:Workshop / Seminar:GLNT: A description of the integral depth-r Bernstein center
DESCRIPTION:Abstract: We give a description of the depth-r Bernstein center for non-negative integers r for a connected reductive group G over a non-archimedean local field\, as a limit of depth-r standard parahoric Hecke algebras. Using this description\, we produce elements of the depth-r center by constructing a map to the depth- r center from a certain subalgebra ( which we call stable functions) of the algebra of invariant functions on the r-th Moy Prasad filtration quotient  of hyperspecial parahorics. We use these elements to attach an invariant to each depth-r irreducible representation\, and show that this is equal to the semi-simple part of minimal K-types contained in the irreducible representation. This talk is based on a joint work with Tsao-Hsien Chen.

SUMMARY:Livestream / Virtual:ISRMT Seminar: Critical phenomena in the 2-matrix model: the Ising model coupled to gravity
DESCRIPTION:The unitary invariant ensembles of random matrix theory (collectively referred to as the `1-matrix model’) are one of the central objects of study in the theory of random matrices. Upon tuning the parameters of this model\, one can realize certain `higher-order' eigenvalue correlations at the endpoints of the density of eigenvalues. In the 1-matrix model\, these higher-order correlation kernels can be written in terms of special solutions of the Painlevé I and II hierarchies. We refer to such special tunings as critical phenomena.\n\nThe 2-matrix model is an extension of the 1-matrix model\, which came to be well-studied in part because it admits a much richer class of critical phenomena. In this talk\, I will survey some of the conjectures regarding these critical phenomena from the physics literature\, and discuss some of the physical implications of these results. In particular\, I will discuss some forthcoming work (joint with Maurice Duits and Seung-Yeop Lee) regarding a special critical phenomenon in the 2-matrix model\, which has implications in the theory of the Ising minimal model coupled to topological gravity.\n\nEmail eblackst@umich.edu for the zoom link.

SUMMARY:Lecture / Discussion:Putting the Black Back in the Mediterranean: The De/facement of Whiteness and European Innocence in Contemporary Greek Society
DESCRIPTION:It is commonly assumed that Greece\, like other countries in the Balkan region\, is not a place where we need to discuss race\, anti-blackness\, white supremacy\, or even European colonial histories. This talk\, by contrast\, draws on Penelope Papalias’s experience as a founding member of the initiative dëcoloиıze hellάş and training in historical anthropology at the University of Michigan to make a case for the hidden centrality of coloniality and white supremacy to myths of Greek nation and modernity. Drawing on two ethnographic case studies\, Professor Papailias uses a critical keyword of the decolonial movement\, defacement\, to make a case for the historic whitening (not inherent whiteness) of the Mediterranean given the connectedness of modern Greece to the project of European modernity.\n\nPenelope Papailias is Αssociate Professor of Social Anthropology at the University of Thessaly\, where she directs the Pelion Summer Lab for Cultural Theory and Experimental Humanities. Having grown up in New York City\, the child of a Greek immigrant\, and studied English literature at Harvard (B.A) and cultural anthropology at the University of Michigan (Ph.D.) before returning/migrating to her father’s homeland\, she is especially critical of the role of knowledge production in national mythologies and narratives of settler colonial states. Her research centers on historical culture\, the politics of memory and monuments\; media events\, affective networks and witnessing of violence/death of the Other in/as the public sphere\; necropolitics\, ecocide\, decoloniality and black geographies in the Greek context\; experimental pedagogies and public anthropology. Among her publications are Genres of Recollection: Archival Poetics and Modern Greece (Palgrave Macmillian\, 2005)\, Digital Ethnography (Kallipos\, 2015\, with P. Petridis)\, A Call to Rasanblaj: Black Feminist Futures & Ethnographic Aesthetics (ed.\, Rosa Luxemburg Greece\, 2023) and Greek Colonialities (ed.\, Rosa Luxemburg Greece).
