SUMMARY:Workshop / Seminar:GEOM SEMINAR:  On Measures Invariant under Horospherical Subgroups in Rank One Lie Groups
DESCRIPTION:Given a positive Laplace eigenfunction on a hyperbolic manifold\, there exists a horospherically invariant measure corresponding to it\, known as the Burger-Roblin measure. A question attributed to Babillot concerns whether every horospherically invariant measure arises from such a correspondence. In this talk\, I will survey previous works where affirmative answers to this question were found and present a new result extending it to a broad class of subgroups in rank one Lie groups. This is joint work with Or Landesberg\, Elon Lindenstrauss\, and Hee Oh.

SUMMARY:Lecture / Discussion:Linguistics Graduate Student Colloquium
DESCRIPTION:Demet Kayabaşı\nPhD Candidate - Department of Linguistics \n\nTitle: Emphatic Markers & Encoding of Event Participants \nin the Syntax-Semantics Interface \n\nAbstract: Anaphoric items like “myself” are widely studied in relation to dependency phenomena  like reflexivity (e.g. “I hurt myself.”). Reflexives interact with the argument structure  and can saturate A-positions across languages (Faltz 2016\, Büring 2005). However\, it is  also cross-linguistic common for the same anaphors in some languages also mark a  relation that does not alter the argument structure while still maintaining a co-referential  relationship with an argument (Dechaume & Wiltschko 2017 i.a.)\, also known as an emphatic marker (e.g. “I tied my shoelaces myself.”). Using data from both spoken and signed languages\, this  talk presents an analysis of both the event and information structural role of anaphors\, and why the functions  go together. \n\n\nYu-Chuan Lucy Chiang\nPhD Candidate - Department of Linguistics \n\nTitle: Acquisition of light verb syntax by Mandarin Bilinguals \n\nAbstract: This talk discusses the acquisition of the syntax of so-called light verb constructions in  Mandarin by adult English-Mandarin heritage bilinguals and adult L2  Mandarinspeakers. Light verbs contribute limited semantic content in the verb phrases  they form with dependent nouns in Mandarin (Huang 2015\; Lin 2014). Questions arise  as to how the verb phrase da dianhua ‘(tele)phone/call (someone)’ can be formed in  parallel to the lexical meaning ‘hit (the) telephone’. Some syntactic structures can be used to distinguish the two meanings\, such as passives and topicalization. Since these structures involve complex syntax and semantics properties\, the acquisition of light verbs raises some  interesting questions about bilinguals. An online acceptability judgment experiment via PCIbex was  conducted to address such questions. Based on the results\, Mandarin-English bilinguals’ judgments on light  verbs showed distinct patterns\, suggesting that the grammar of Mandarin light verbs differs among the three  groups of speakers.\n\nThis event will be hybrid\, as well as zoom https://umich.zoom.us/j/91857099548.

SUMMARY:Workshop / Seminar:Michigan Lectures in Algebraic Geometry: New perspectives on the topology of algebraic maps III
DESCRIPTION:Given a proper algebraic map f : X--> Y\, the decomposition theorem of Beilinson\, Bernstein\, Deligne\, and Gabber provides powerful tools to the study of its topology. This endows the cohomology of X with an extra structure\, known as the perverse filtration\, which measures the singularities of the map f. In recent years\, the decomposition theorem and the induced perverse filtration have been found to share surprising connections to other branches of mathematics\; these include non-abelian Hodge theory (the P=W conjecture)\, enumerative geometry (Donaldson-Thomas and BPS invariants)\, planar singularities (DAHA\, knot invariants)\, and hyper-Kähler geometries (Hodge modules\, motivic techniques). In this lecture series\, I will discuss some of these developments. If time permits\, open questions will be presented and discussed.
