Speaker: Daniel Soskin (IAS)Title: Multiplicative inequalities for totally matricesAbstract: Totally positive matrices are matrices in which each minor is positive. Lusztig extended the notion to reductive Lie groups. He also proved that specialization of elements of the dual canonical basis in representation theory of quantum groups at q=1 are totally non-negative polynomials. Thus, it is important to investigate classes of functions on matrices that are positive on totally positive matrices. I will discuss multiplicative determinantal inequalities as a source of such functions. In the joint work with M. Gekhtman, we have shown that the set of multiplicative inequalities is finitely generated for matrices of any order. In the joint project with M. Gekhtman and Z. Greenberg we provide a list of all generators of multiplicative determinantal inequalities for the case of square matrices of order 4. We also extend the problem of description of multiplicative inequalities in minors to inequalities in all cluster variables of finite type cluster algebras. We show that the generators of these sets of inequalities are in bijection with cluster variables, and are associated to sinks in fully sources/sinks orientation of the associated Dynkin diagram in the exchange graph of the finite type cluster algebras.

architects have turned to domain-specific hardware accelerators to improve the performance and efficiency of computing systems. However, programming these systems entails significant modifications to the software stack to properly leverage the specialized hardware. Moreover, the accelerators become obsolete quickly as the applications evolve. What is needed is a structured approach for generating programmable accelerators and for updating the software compiler as the accelerator architecture evolves with the applications. In this talk, I will describe a new agile methodology called AHA for co-designing programmable hardware accelerators and compilers. Our methodology employs a combination of new programming languages and formal methods to automatically generate the accelerator hardware and its compiler from a single specification. This enables faster evolution and optimization of accelerators, because of the availability of a working compiler. I will showcase this methodology using three generations of coarse-grained programmable accelerator chips that we designed using this flow: (1) Amber, that targets dense image processing and machine learning, (2) Onyx, that optimizes dense performance over Amber and additionally supports sparse tensor algebra and finally (3) Opal, that further optimizes for sparse machine learning applications.Bio: Priyanka Raina received the B.Tech. degree in Electrical Engineering from IIT Delhi in 2011, and the M.S. and Ph.D. degrees in Electrical Engineering and Computer Science from MIT in 2013 and 2018, respectively.

Professor Lisa Koch from Claremont McKenna College will speak at the MIT Security Studies Program's Wednesday Seminar.When leaders issue nuclear threats, how are those threats perceived? A nuclear threat should lack credibility because carrying out the threat could trigger massive retaliation of some kind. Nonetheless, nuclear threats are not simply dismissed as non-credible. Instead, nuclear threats appear to inspire fear. In this seminar, Professor Koch will present her research on how US decision-makers perceive and respond to 21st-century nuclear threats.

Consciousness & Reality (C&R) Colloquium 2024-25 SeriesQUANTUM PROCESSING IN THE BRAIN?MATTHEW FISHER Professor of Physics, University of California Santa BarbaraThe endeavor to construct a laboratory quantum computer has evolved into a multi-billion-dollar undertaking. However, an intriguing question arises: could we ourselves be quantum computers? While maintaining quantum coherence on macroscopic time scales is exceedingly unlikely in the warm wet brain, there is one exception: Nuclear spins. Our strategy is one of reverse engineering, seeking to pinpoint the biochemical substrate and mechanisms that might underpin the hypothetical quantum processing involving nuclear spins. Seemingly, a specific neural qubit and a unique collection of ions, molecules and organelles can be identified. I will present an overview of our (largely experimental) ongoing efforts to delve into this captivating realm of exploration.ABOUT THE EVENT This lecture will be accessible to an interdisciplinary audience. Caltech, Stanford, MIT and IMICS members from all divisions are welcome to join. Select questions from the Q&A window will be answered after the lecture.ABOUT THE SERIES The Consciousness & Reality colloquium series promotes interdisciplinary investigations on mind, cognition, consciousness, and the nature of reality. This colloquium is the second in the 2023-24 series

Speaker: Griffin Wang (IAS)Title: Tetrahedral Symbol and Relative Langlands DualityAbstract: In the quantum theory of angular momentum, the Racah--Wigner coefficient, often known as the 6-j symbol, is a numerical invariant assigned to a tetrahedron with half-integer edge-lengths. The 6 edge-lengths may be viewed as representations of SU(2) satisfying certain multiplicity-one conditions. One important property of the 6j symbol is its hidden symmetry outside the tetrahedral ones, originally discovered by Regge.In this talk, we explore a generalized construction, dubbed tetrahedral symbol, in the context of rank-1 semisimple groups over local fields, and explain how the extra symmetries may be explained by relative Langlands duality. Joint work with Akshay Venkatesh.
