Victor L. Shapiro Distinguished Lecture in Mathematics
January 27th, 2021, 12:00 - 12:55 p.m. (PST)
Dr. Jean-Francois Le Gall, Professor of Mathematics, Université Paris-Saclay
Brownian Geometry on the Sphere
Much recent work has been devoted to the metric properties of large random graphs drawn on the two-dimensional sphere, which are also called random planar maps. Starting from a triangulation of the sphere with a given number of faces (triangles) and chosen uniformly at random, one considers the metric space consisting of the vertex set of this triangulation equipped with the graph distance.When the size of the triangulation tends to infinity, this suitably rescaled random metric space converges in distribution, in the Gromov-Hausdorff sense, to a random compact metric space called the Brownian sphere (or Brownian map). We will survey recent results showing that the Brownian sphere is, indeed, a universal model of random geometry in two dimensions. If time permits, we will also introduce related models such as the Brownian disk and the Brownian plane, and we will discuss their connections with the Brownian sphere.The speaker will be available for an informal questions and answers session and discussion for half-an-hour following the lecture.
Bio: Professor Jean-Francois Le Gall is a distinguished French mathematician working in probability theory (including the theory of Brownian motion), random trees, the Brownian snake, stochastic processes and their connections with partial differential equations.He is a member of the French Academy of Sciences and was awarded the Davidson Prize (in 1986), the Fermat Prize (in 2005), as well as (in 2019) the Wolf Prize in Mathematics. He was awarded his Ph.D. in 1982 from the Université Pierre et Marie Curie (Paris VI) and is a Professor at the Université Paris-Sud Orsay, now part of the Université Paris-Saclay.
MICROTUTORIALS
When learning calculus at college level, students often encounter difficulties overcoming word problems, or extracting mathematics from the context of a certain subject. The instructors also encounter time limitations to teaching with sufficient depth, coverage and illustrations.
The Microtutorials in Mathematics project team at UCR has conceived a new approach to producing supplementary instructional materials. It produces a collection of microtutorials as supplementary instructional and learning materials. The intent is to assist the students and instructors to overcome such difficulties and pressures, with the help of online learning. The students could use them freely on any topics of their choice. The videos are produced with follow-up questions to enable instructors to flip their classrooms if desired.
Math Alliance: Providing educational success to underrepresented and first-generation students is an important part of UCR's mission.
The National Alliance for Doctoral Studies in the Mathematical Sciences - Math Alliance - is a community of math sciences faculty and students with the following goals:
- To increase the number of doctoral degrees in the mathematical sciences among groups that have been traditionally underrepresented in those fields.
- To improve placement of students from these groups in doctoral programs in disciplines that recruit undergraduate mathematics majors.
- To increase the number of Phds from these groups who enter the professoriate in the mathematical sciences as well as other appropriate professions.
- To increase funded research collaborations among faculty members at the universities with mathematical sciences doctoral programs and faculty members at colleges and universities focused on undergraduate students.
- To foster the growth of a community of mathematical scientists that promotes a diverse workforce.
If you are interested in becoming a Math Alliance Scholar, please feel free to contact Dr. Fred Wilhelm. The benefits include access to Math Alliances Facilitated Graduate Applications Process and possible funding to go the the Alliance's Field of Dreams conference.
