SUMMARY:Tropical linear series and matroids (Dagan Karp\, HMC)
DESCRIPTION:In this talk\, I’ll attempt to give a friendly introduction to tropical linear series and explore their relationship to matroid theory. Along the way\, we’ll stop to admire the beautiful view from enumerative geometry and combinatorics. This is joint work with Chih-Wei Chang\, Matthew Dupraz\, Hernan Iriarte\, David Jensen\, Sam Payne\, and Jidong Wang\, and also with Jenna Luo.

SUMMARY:The alchemy of mixing mathematics:  The second annual CCMS workshop in the history and philosophy of mathematics
DESCRIPTION:This one-day workshop assembles diverse perspectives from the history and philosophy of mathematics to examine ways in which mathematics interacts and expands across other fields of study. \nPlease RSVP here by Monday\, April 6th to attend the workshop and lunch. \n\nSchedule \n10:00 to 10:05 Welcome! \n10:05 to 11:05 Otávio Bueno (University of Miami & Tohoku University)\, “Why there are no styles of mathematical reasoning” \n11:10 to 12:10 E. L. Meszaros (Brown University)\, “Algorithmic translations and interpretations of late Babylonian mathematics” \n12:10 to 1:20 Lunch \n1:25 to 2:25 Jed Buchwald (CalTech)\, “The winding trail to Newton’s Principia” \n2:30 to 3:30 Mate Szabo (University of Southern California)\, “Turing’s machines and Max Newman’s symbolic machinery for mathematical physics” \n\nAbstracts \n\nOtávio Bueno (University of Miami & Tohoku University)\, “Why there are no styles of mathematical reasoning” \nThe notion of style of scientific reasoning has been used as an analytical tool for the characterization of significant features of scientific practice (in particular\, by Crombie [1994]\, Hacking [2002]\, and Granger [1988]). Styles of scientific reasoning are different from scientific theories in a given domain of inquiry: styles are broader than theories\, and they are not so dependent on features of the particular domain. In this work\, I have two main goals. I’ll first provide a characterization of the concept of style of reasoning that overcomes some difficulties that have been raised against this tool (by Bolduc [2014]). I’ll then argue that\, despite the broad conception of style I defend\, there is no suitable way of formulating a notion of style of mathematical reasoning. Mathematics\, I’ll argue\, is too malleable\, and attempts at characterizing a notion of style in geometry\, analysis\, algebra or set theory end up yielding just more mathematical theories particular to these domains. Mathematical practice is significantly different from scientific practice in this respect. \nE. L. Meszaros (Brown University)\, “Algorithmic translations and interpretations of late Babylonian mathematics” \nInitial investigations into Babylonian mathematics as “algorithms” began\, intuitively\, by interrogating the large corpus of Old Babylonian mathematical texts. Donald Knuth viewed these prose maths problems as examples of algorithms\, though many scholars of Babylonian cultures and languages disagreed with this characterization. However\, recent studies have demonstrated the value of looking for algorithms among other corpora\, particularly astronomical texts. While astronomical procedures demonstrated more algorithmic characteristics\, they also highlighted uniquely Babylonian tendencies. Whether these texts can be truly considered “algorithmic” becomes less important than whether the algorithmic lens as a tool of analysis can shed light on new aspects of the science and mathematics contained within the tablets. This talk examines the application of the term “algorithm” to less frequently considered Late Babylonian mathematics. While this corpus remains small\, the few examples that have been recovered show characteristic differences from their Old Babylonian counterparts\, making it valuable to reconsider the application of the term algorithm and the algorithmic lens of investigation. Beginning with an introduction to the corpus and what makes it different from earlier mathematical texts\, this talk then makes the case for viewing these later texts algorithmically. Comparisons to Babylonian algorithmic forms and cultures\, particularly arising from the astronomical sciences\, will be made and evaluated for use within the field. \nJed Buchwald (CalTech)\, “The winding trail to Newton’s Principia“ \n\nThroughout the years between his first engagement with mathematics under Isaac Barrow and the production of the manuscript that evolved into Book I of the Principia\, Newton was only sporadically engaged by issues of motion\, whether earthly or astronomical. His first concerted interest involved collisions\, which he modeled on the material circumstances of a springlike mechanism. In doing so\, and in a subsequent turn to circular motion\, the young Newton presumed without comment what would later be formalized as the Principia‘s three laws of motion. He was hardly the only one\, at least in England\, to make such presumptions. We will discuss this early work in order to unpack what transpired when\, in 1679\, Newton responded to a letter from Robert Hooke\, his former critic in optics. We’ll then consider what in consequence took place following the famous visit to Newton by Edmond Halley in 1684. If time allows\, we’ll conclude with a brief examination of the interesting reaction of the mathematician John Wallis to Newton’s manuscript account of fall under resistance\, sent to Wallis for comment by Halley two years before the Principia. In so doing we will see that the fundamental key to the novelty of Newton’s work at that time consisted in the specific manner according to which he discretized motion change. \nMate Szabo (University of Southern California)\, “Turing’s machines and Max Newman’s symbolic machinery for mathematical physics” \nWhile Turing’s “On Computable Numbers…” from 1936 and its impact is well studied\, much less is known about Turing’s early influences. The aim of this talk is to show how Max Newman\, who taught Turing in Cambridge and was later his boss in Bletchley Park and at the University of Manchester\, influenced his early work. Indeed\, Turing’s interest in the “Entscheidungsproblem” stemmed from Newman’s lectures on the foundations of mathematics he attended in 1935. While Newman is known as a combinatorial topologist\, he was the first to teach a modern\, Hilbert style mathematical logic course in the UK. In addition\, he frequently engaged with the Cambridge philosophers during the 1920s and 1930s. His interest in scientific philosophies most likely stems from his visit to Vienna during the 1922/1923 academic year\, where he came in touch with members of the famous Vienna Circle. Indeed\, his unpublished dissertation\, The Foundations of Mathematics from the Standpoint of Physics (1923)\, shows strong influences of the Vienna Circle. Newman’s aim in the dissertation is to build up mathematical physics as a “symbolic machinery” for manipulating “a body of ‘logical axioms’ and a set of ‘physical assumptions’”. This leads to the parallel development of an ‘epistemic logic’ to deal with ‘beliefs’ and ‘judgements about sensations’ on the physical side\, and the description of logic as acts\, performances and processes of symbol manipulation. After a careful look at the dissertation I will bring out the surprisingly strong resemblances (as well as the important differences) between Newman’s treatment of mathematical activities and Turing’s analysis of the human “computor”.

SUMMARY:Extremal Eigenvalues of Weighted Steklov Problems (Chiu-Yen Kao\, CMC)
DESCRIPTION:Abstract: We study the optimization of Steklov eigenvalues with respect to a boundary density function ρ on a bounded Lipschitz domain. We investigate the minimization and maximization of a Steklov eigenvalue over admissible densities satisfying pointwise bounds and a fixed integral constraint. We establish the existence of optimal solutions and provide structural characterizations: minimizers are bang-bang functions and may have disconnected support\, while maximizers are not necessarily bang-bang. On circular domains\, the minimization problem admits infinitely many minimizers generated by rotational symmetry\, while the maximization problem has infinitely many distinct maximizers that are not symmetry-induced. We also show that an eigenvalue is generally neither convex nor concave with respect to the density function\, limiting the use of classical convex optimization tools. To address these challenges\, we analyze the objective functional and introduce a Fréchet differentiable surrogate that enables the derivation of optimality conditions. We further design an efficient numerical algorithm\, with experiments illustrating the difficulty of recovering optimal densities when they lack smoothness or exhibit oscillations.
