SUMMARY:Emer Lopera Arias (HMC)
DESCRIPTION:Title: The fractional p-Laplacian operator. Motivation for its definition and related boundary value problems \nAbstract: \nLast decades\, nonlocal operators\, as the fractional Laplacian\, have gained to much attention due to its applications to several physical Phenomena. In this talk we aim to motivate the definition of the fractional laplacian operator through a simple but quite illustrative example related to Long jump random walks. then\, we will present a generalization to the fractional p-laplacian operator\, p>1\, and we will show a new result concerning the existence of solutions for a boundary value problem with this operator.

SUMMARY:Negligible cohomology (Matthew Gherman\, Caltech)
DESCRIPTION:For a finite group G\, a G-module M\, and a field F\, an element u in H^d(G\,M) is negligible over F if for each field extension L/F and every continuous group homomorphism from Gal(L^{sep}/L) to G\, u is in the kernel of the induced homomorphism H^d(G\,M) to H^d(L\,M). Negligible cohomology was first introduced by Serre and has deep connections with the embedding problem\, cohomological invariants\, and the profinite inverse Galois problem. Professor Alexander Merkurjev (UCLA) and I were able to compute negligible cohomology in degree 2\, compute the mod p negligible cohomology of elementary abelian p-groups\, and determine the Krull dimension of the quotient of mod p cohomology by the ideal of negligible elements.

SUMMARY:Claremont Topology Seminar: Elena Wang (Michigan State University)
DESCRIPTION:We welcome all undergraduates and graduate students to attend topology seminar! \nSpeaker: Elena Wang (Michigan State University) \nTitle: A Distance for Geometric Graphs via the Labeled Merge Tree Interleaving Distance \nAbstract: Geometric graphs appear in many real-world data sets\, such as road networks\, sensor networks\, and molecules. We investigate the notion of distance between graphs and present a metric to measure the distance between two geometric graphs via merge trees. In order to preserve as much useful information as possible from the original data\, we introduce a way of rotating the sublevel set to obtain the merge trees via the idea of the directional transform. We represent the merge trees using a surjective multi-labeling scheme\, and then compute the distance between two representative matrices. Our distance not only has theoretically desirable qualities but can also be approximated in polynomial time. We illustrate its utility by implementation on a Passiflora leaf data set.

SUMMARY:CCMS Colloquium: Inaugurual Barbara Beechler Lecture
DESCRIPTION:CCMS Colloquium invites you to the final talk of the 2023-2024 academic year and the inaugural Barbara Beechler Lecture by Professor Judy Grabiner\, Flora Sanborn Pitzer Professor of Mathematics Emerita. \nTitle: It’s All for the Best: Optimization in the History of Science \nAbstract: Many problems\, from optics to economics\, can be solved mathematically by finding the highest\, the quickest\, the shortest – the best of something. This has been true from antiquity to the present. Why did we start looking for such explanations\, and how did we conclude that we could productively do so? Scientific examples will include problems from ancient optics\, and more modern questions in optics and classical mechanics\, drawing on ideas from Newton’s and Leibniz’s calculus and from the Euler-Lagrange calculus of variations. A surprising role will also be played by philosophical and theological ideas\, including those of Leibniz\, Maupertuis\, MacLaurin\, and Adam Smith. \nSpeaker Bio: Judith V. Grabiner received her B.S. in mathematics with honors from the University of Chicago\, and her PhD at Harvard in the History of Science\, with advisors I Bernard Cohen and Dirk Struik. For fourteen years she was a Professor of History at California State University\, Dominguez Hills\, and then for thirty years was Professor of Mathematics at Pitzer College. She has also taught at various times at Harvard\, UC Santa Barbara\, Cal State LA\, UCLA\, Pomona College\, and the University of Leeds in England. \nHer publications have received three Carl B. Allendoerfer Awards for the best article in Mathematics Magazine\, and she is the only four-time winner of the MAA’s Lester Ford award for best article in the American Mathematical Monthly. In 2003 she received the MAA’s Haimo award for teaching mathematics\, principally for her courses in mathematics for liberal arts students. In 2014 her book A Historian Looks Back: The Calculus as Algebra and Selected Writings won the Beckenbach Book Prize from the MAA. She is a Fellow of the American Mathematical Society\, and in 2021 won the Albert Leon Whiteman prize from the AMS for what they called “her outstanding contributions to the history of mathematics\, in particular her works on Cauchy\, Lagrange\, and MacLaurin; her widely-recognized gift for expository writing; and a distinguished career of teaching\, lecturing\, and numerous publications promoting a better understanding of mathematics and the significant roles it plays in culture generally.” \n
