SUMMARY:Workshop / Seminar:On the Algebra of Moving Window Calculations
DESCRIPTION:Moving window calculations arise throughout applied mathematics\, computer science\, and engineering. Familiar examples include moving sums\, maxima\, and filters\, but the same basic problem also appears in more general windowed recurrences. In this talk\, we show that a large class of such calculations admits a common algebraic formulation. In the associative setting\, moving window calculations can be recast as exponentiation in a semidirect product\, bringing efficient powering algorithms to bear. In more general settings\, semi-associativity provides the right framework for representing compositions of updates and understanding when efficient computation is still possible. This point of view not only unifies a broad family of examples\, but also leads naturally to compact vectorized implementations\, making the methods well suited to modern GPU architectures. This is joint work with David Maslen.

SUMMARY:Film Screening:Sky Tonight
DESCRIPTION:A live presentation on what to find in the sky tonight and for the coming few weeks. This presentation includes how to find the cardinal directions with the North Star\, current and upcoming constellations\, visible planets\, a few deep sky objects depending on the season\, and other interesting astronomical visualizations. If you want to be able to look up from your own backyard and know what to look for\, this is the show for you.

SUMMARY:Lecture / Discussion:Steffy Lecture: Irina Dolinskaya\, NSF
DESCRIPTION:Abstract\nLooking back on my professional journey\, I am struck by how much of it was shaped by people\, opportunities\, and experiences I could not have anticipated as a student at the University of Michigan.\n\nIn this talk\, I will reflect on my journey from the University of Michigan’s Industrial and Operations Engineering program to my current role as a Directorate Head at the National Science Foundation\, and how my Michigan education prepared me for the opportunities and challenges along the way. I will share lessons learned about\nleadership\, collaboration\, resilience\, and the importance of remaining open to unexpected opportunities.\n\nI hope to encourage students to build a strong foundation\, stay curious\, embrace opportunities\, and recognize that a meaningful career does not always follow a predictable path.\n\nBiography \nDr. Irina Dolinskaya is the Directorate Head for Computer and Information Science and Engineering at the U.S. National Science Foundation (NSF). Previously\, she served as Deputy Division Director and Program Director at NSF and as a faculty member in Industrial Engineering and Management Sciences at Northwestern University.\n\nA proud Michigan alumna\, Dr. Dolinskaya earned her M.S. and Ph.D. in Industrial and Operations Engineering from the University of Michigan and her B.S. in Industrial Engineering from the University of Florida. Her research focuses on transportation science and logistics\, including humanitarian logistics\, vessel performance\, and electric vehicle routing. She credits her education at Michigan as an important foundation for her academic and professional journey.

SUMMARY:Workshop / Seminar:Student Algebraic Geometry: Compactifications of Siegel Modular Varieties
DESCRIPTION:The Siegel upper half-space H_g serves as a natural generalization of the upper half-plane. Indeed\, just as M_{1\,1} = A_1 is the quotient H/SL_2(Z)\, one can show that A_g\, the space of principally polarized abelian varieties of dimension g\, is isomorphic to H_g/Sp_{2g}(Z). More generally\, one can consider spaces H_g/Gamma for any arithmetic subgroup Gamma in Sp_{2g}(Q). Unlike M_g\, which admits the canonical Deligne-Mumford compactification\, these spaces admit many natural compactifications with different geometric properties. In this talk\, we introduce H_g/Gamma\, the Siegel modular varieties\, and discuss various compactifications such as the Baily–Borel compactification and toroidal compactifications. We then focus on the specific case of g = 2 to showcase the beautiful arithmetic that occurs even in this small case.
