SUMMARY:Lecture / Discussion:HET Seminar | Renormalization Group in far-from-equilibrium states
DESCRIPTION:We study renormalization group flows in far-from-equilibrium states. The study is made tractable by focusing on states that are spatially homogeneous\, time-independent\, and scale invariant. Such states\, in which mode k has occupation number $n_k = k^{-\gamma}$\, are well-known in nonlinear physics (going under the name of wave turbulence). RG flow in such states is qualitatively different than in the vacuum -- a positive $\gamma$ decreases the dimension of an operator\, turning marginal interactions into relevant interactions. We compute one loop beta functions. Depending on the sign of the beta function\, backreaction may either cause a minor shift of the state in the IR\, or completely change the nature of the state. Focusing on nearly marginal interactions\, we construct an analog of the epsilon expansion and IR fixed points\, with epsilon now set by the scaling of the interaction rather than the spacetime dimension. In the language of RG flow\, critical balance scaling -- having applications in fields as varied as astrophysics and ocean waves -- corresponds to the state dynamically adjusting itself along the RG flow until the interaction becomes marginal.

SUMMARY:Lecture / Discussion:Linguistic Anthropology Colloquium | “‘Natural’ Elites: Semiotics of Language and Personhood at a Philippine University”
DESCRIPTION:How do people conceptualize human nature? How does it become an object of perception and experience\, an entity toward which value\, action\, or politics can be formulated? This talk will consider nature as both a folk concept and an analytic concept in my ethnographic research on Philippine elite formations. First\, I will explore how linguistic and semiotic anthropology have dealt with the question of nature\, outlining three areas across the literature: naturality\, naturalization\, and naturalism. Then\, I will draw on my fieldwork at a private university in the Philippines to explore how college student participants discussed becoming an elite “naturally\,” and being a “natural” elite. My participants conceived of nature as involving reinvention\, thus formulating an essence as artificial\, accomplished through will or adaptation. I argue that naturalizing elites helps naturalize the political economic systems that sustain them\, framing a world that can be regretted but not changed.\n\nAngela Reyes is Professor of English and Anthropology at the City University of New York (Hunter College and the CUNY Graduate Center). Her research examines historical and contemporary formations of language and personhood in the U.S. and the Philippines. Her books include The Oxford Handbook of Language and Race (co-edited with H. Samy Alim and Paul Kroskrity)\, Discourse Analysis Beyond the Speech Event (co-authored with Stanton Wortham)\, Beyond Yellow English: Toward a Linguistic Anthropology of Asian Pacific America (co-edited with Adrienne Lo)\, and Language\, Identity\, and Stereotype Among Southeast Asian American Youth: The Other Asian.

SUMMARY:Tours:LSA Campus Tours for Transfer Students
DESCRIPTION:Tired of campus tours designed for high school students? Join the LSA Transfer Student Ambassadors for a central campus tour and to learn all about the transfer student experience. As transfer students\, the Ambassadors understand the questions you have and designed a tour with the needs of transfer students in mind.\n\nAfter the tour\, staff members from the LSA Transfer Center will be available to answer your questions about transfer credit\, financial aid\, and applying.\n\nPlease register using the link to the right.

SUMMARY:Lecture / Discussion:RIW Colloquium: Marleen Rozemond (University of Toronto)
DESCRIPTION:Brought to you by Early Modern Philosophy Working Group (a Rackham Interdisciplinary Workshop)\n3222 Mason Hall\nTitle: Why Matter can’t think: Suárez\, Descartes\, and Leibniz on Things and Properties\n\nAbstract: Descartes spoke of properties of things as modes: thus sizes and shapes are modes of bodies.  This notion had its roots in the scholastic tradition and was well developed in the thought of Francisco Suárez.  It became quite important in the early modern period\, but its significance has not been fully appreciated.  In this paper I discuss a crucial early modern change in the notion of a mode and its role in related\, yet interestingly different\, arguments against thinking matter in Descartes and Leibniz.

SUMMARY:Meeting:SoConDi
DESCRIPTION:The SoConDi group is both a discussion platform and a study group for students and faculty members who are interested in sociolinguistics\, language contact\, discourse analysis and related disciplines including linguistic anthropology. Members of the SoConDi group present their work in progress from time to time\, and discuss current issues in the disciplines\, or study selected readings together.

SUMMARY:Workshop / Seminar:Student Algebraic Geometry: Extending the Period Map
DESCRIPTION:For families of smooth algebraic varieties\, we have the period map from the parametrizing space to the period domain. In this talk\, we will consider some cases when the ‘period map’ still makes sense if the family has certain type of singular fibers.
