SUMMARY:Workshop / Seminar:Probability and Analysis Seminar: Non-abelian Hirota–Miwa Equations for the KPZ Universality Class
DESCRIPTION:Abstract: The KPZ universality class is a broad collection of mathematical and physical models linked through their shared universal scaling behavior. A privileged subset\, known as exactly solvable models\, possess algebraic structure that allows for exact formulas for their probability distributions.\n\nFor an even smaller subset of these models\, their distributions have been shown to satisfy nonlinear equations from classical integrable systems\, including Painlevé\, KP\, and Toda equations. Why should equations from soliton theory appear in random growth\, and why do they keep reappearing across different models?\n\nI will describe a framework that gives a common algebraic explanation and extends this connection to eighteen exactly solvable models. The framework organizes the Fredholm determinant formulas of solvable KPZ models into an overdetermined linear problem whose compatibility conditions reveal a discrete integrable structure gauge equivalent to the non-abelian Hirota–Miwa equation.

SUMMARY:Workshop / Seminar:Robust and Risk-Sensitive Acceleration in Gradient Methods
DESCRIPTION:First-order methods such as gradient descent (GD) are foundational in optimization. In unconstrained problems with exact gradients\, momentum-based methods—most notably Nesterov’s accelerated gradient descent (AGD) and Polyak’s heavy-ball (HB) method—achieve faster convergence by improving dependence on the condition number. However\, this acceleration comes at a cost: momentum amplifies gradient noise\, making these methods less robust than GD under standard parameter choices and requiring more accurate gradient estimates to attain comparable accuracy. Similar challenges arise in convex and nonconvex min–max optimization.\nMotivated by applications in machine learning\, this talk studies unconstrained and min–max optimization under deterministic\, unbiased stochastic\, and biased stochastic gradient noise. I will present new algorithms that achieve optimal robustness against different noise types\, using control-theoretic tools such as the H_2​ norm\, the H_∞​ norm\, and the risk-sensitivity index\, together with coherent risk measures. I will also discuss worst-case noise constructions and high-probability convergence guarantees. This perspective builds a bridge between optimization and robust control theory and enables the design of noise-robust and risk-sensitive accelerated methods.\nRepresentative Publications:\nM.

SUMMARY:Lecture / Discussion:Manoogian Postdoctoral Lecture | Purist Pursuits: Language\, Global Ideas\, and the Creation of Western Armenian in the Ottoman Empire
DESCRIPTION:This lecture follows Armenians in the Ottoman Empire through a dramatic linguistic transformation\, the aftershocks of which are still being felt today throughout the Armenian diaspora. It chronicles how and why Armenians in the Ottoman Empire fashioned a new language called Western Armenian in the eighteenth\, nineteenth and early twentieth centuries and explores the evolution of an ever-changing ideology that undergirded all phases of the language's formation: linguistic purism. Manoukian will examine the power of global intellectual movements in crafting new language ideologies in the Ottoman Empire and reimagines what language histories can be for Ottoman-era language communities.\n\nJennifer Manoukian is a historian of language. Her work explores the language practices and ideologies of Armenians in the Ottoman Empire and post-genocide diaspora. She earned her PhD in Near Eastern Languages and Cultures from the University of California\, Los Angeles\; her MA in Middle Eastern\, South Asian and African Studies from Columbia University\; and her BA in French and Middle Eastern Studies from Rutgers University. She is the author of *Purist Pursuits: Language\, Global Ideas\, and the Creation of Western Armenian in the Ottoman Empire* and two book-length literary translations from Western Armenian: *The Gardens of Silihdar by Zabel Yessayan* and* The Candidate by Zareh Vorpouni*. She is also the author of a number of articles and the co-founder of Gesaria Armenian Research and Academic Services.\n\nCosponsors: Center for Middle Eastern and North African Studies\, Department of Middle East Studies\, Department of Linguistics\, Department of Anthropology\, and NAASR.
