SUMMARY:Workshop / Seminar:GLNT: The Swan conductor function of an l-adic sheaf on rigid annulus is convex
DESCRIPTION:Abstract: For a given étale l-adic sheaf F on rigid space X\,  the Swan conductor\, a measure of wild ramification of F along the special fiber of a formal model of X\, is the l-adic analog of the radius of convergence of solutions of p-adic differential equations on X.  I will show (when X is an annulus) that the function defined by the Swan conductor has properties that mirror those of the radius of convergence function.

SUMMARY:Livestream / Virtual:ISRMT Seminar: The Riemann problem for a discrete conservation law
DESCRIPTION:The hydrodynamics of a system of conservation laws can often be understood by studying solutions to a Riemann problem\, i.e.\, the evolution of step initial data in a hyperbolic system. When dispersion compensates for the large gradients induced by this initial data\, wave-breaking is often resolved by a dispersive shock wave (DSW). An active area of research is the investigation of quantitative features of DSWs in continuum models arising in physical applied mathematics. This talk leverages modern techniques to investigate solutions of the Riemann problem for a semi-discrete conservation law. The semi-discrete model is obtained by applying a first-order centered difference scheme to the spatial derivative of the Hopf equation. Solutions to the Riemann problem reveal a surprisingly elaborate set of solutions to this example system. In addition to discrete analogs of well-known dispersive hydrodynamic solutions—rarefaction waves (RWs) and DSWs—additional unsteady solution families and finite-time blow-up are observed and characterized. We will also compare the dynamics of the Riemann problem to an integrable discretization of the spatial derivative.\n\nEmail eblackst@umich.edu for the zoom link.

SUMMARY:Performance:o modo superior da filosofia (The Superior Mode of Philosophy): A Performance by Djalma Thürler and Duda Woyda
DESCRIPTION:This performance/conference aspires to raise awareness and strengthen decolonial\, queer\, and feminist frameworks from a diverse\, open\, and interdisciplinary perspective. The two Brazilian artists propose that modernity\, insofar a systemic perpetuation of violence and domination\, is fundamental to understand decolonial theories that are built upon the idea of “desocultamento” or unhiding of diverse epistemologies\, grammars\, forms of social\, economic\, political and family organization\, and spirituality.\n\n“o modo superior da filosofia” is part of the “ATeliê voadOR Research Visibilization” project sponsored by the Secretaria de Cultura (Culture Ministry) of the State of Bahia through the Edital de Mobilidade Cultural and CAPES. The purpose of this project is to promote intercultural dialogue\, cooperation\, co-production\, exchange\, and collaboration between artists from Bahia\, Brazil\, and artists in other countries\, in addition to promoting the insertion of Bahia in the international circuit of art and culture.\n\n   Djalma Thürler is a theater director\, dramaturge\, and interdisciplinary researcher with ATeliê voadOR Teatro in Salvador\, Bahia. He holds a PhD from Universidade Federal Fluminense (2006) and is a professor at the Federal University of Bahia (UFBA)\, where he researches queer language\, decolonial aesthetics\, and monstrous theatricalities with the NuCuS research group.\n   \n   Duda Woyda\, also affiliated with ATeliê voadOR Teatro\, is an actor and researcher. He holds a master’s and PhD in culture and society from UFBA and completed a postdoctoral fellowship in 2023.\n\nSponsors: Department of Romance Language and Literature\, Department of Women's and Gender Studies\, Department of American Culture\, and the Latino/a Studies Program.\n\n\nIf there is anything we can do to make this event accessible to you\, please contact lacs.office@umich.edu. Please be aware that advance notice is necessary as some accommodations may require more time for the university to arrange.
