SUMMARY:Workshop / Seminar:RTG Seminar Geometry\, Topology\, Dynamics: Metric Lines in Carnot groups
DESCRIPTION:Among nilpotent Lie groups\, Carnot groups form a particularly important subclass\, with the Heisenberg group being the most well-known example. Carnot groups admit the structure of a sub-Riemannian manifold. Thus\, to broaden the context\, a sub-Riemannian geodesic is a local arc-length-minimizing curve. A natural question is: What are the conditions for a geodesic to be a global minimizer? A curve is called a metric line if it is a globally minimizing geodesic\; an alternative term is “an isometric embedding of the real line.” The talk is devoted to presenting the results and ideas that inspired me to formulate a conjecture classifying metric lines in Carnot groups\, as well as the results obtained in this direction.

SUMMARY:Workshop / Seminar:Student AIM Seminar: Barycentric Lagrange Tree-Traversal Fast Summation Algorithms
DESCRIPTION:Tree-based algorithms are popular methods for the fast summation of particle interactions\, including the Barnes-Hut treecode and the Greengard-Rokhlin fast multiple method\, which reduce the operation count for a given tolerance from O(N) to O(NlogN) and O(N) respectively. Since then\, there have been several improvements to these algorithms to solve different problems. In this talk\, we present the Kernel Independent Treecode (KITC) [1] and the Barycentric Lagrange Dual Tree Traversal (BLDTT) [2] methods\, both of which take advantage of the stability properties of barycentric Lagrange polynomial interpolation which will also be discussed. Additionally\, we will show how these methods are easily parallelizable using CPUs or GPUs\, as well as discussing the performance with examples of problems in fluid and plasma dynamics where these methods have been used. Finally\, we present plans for future implementations of these methods in modeling the solar magnetic field in the solar corona.\n\n[1] L. Wang\, R. Krasny\, and S.

SUMMARY:Social / Informal Gathering:BIndx November meeting: Tiffany Hunt
DESCRIPTION:Please join us for the November BIndx Meeting! There will be food\, games\, and conversation. All majors are welcome. This week's speaker is Managing Director of Transformation Enablement and Operations at KPMG US\, Tiffany Hunt.\n\nThe Black Industrial Engineers (BIndx\, pronounced BIND-ex) group is composed of IOE students and faculty who come together informally for meaningful conversations and fellowship to promote learning\, mentoring\, and networking. The BIndx program was initiated to promote a learning space where students feel comfortable engaging with faculty. BIndx meetings occur as informal monthly discussions to help form relationships between faculty and minoritized students.  BIndx hosts a diverse group of guest speakers throughout the semester with a specific focus to facilitate conversations\, build connections\, and empower self-reflection.\n\nDinner will be served to those who RSVP
