https://wp0.vanderbilt.edu/math/2019/05/shanks-lecture-quantum-computation-via-octonions/
Fri, 03 May 2019 21:30:26 +0000https://wp0.vanderbilt.edu/math/?p=8992I will explain how quantum computation can be carried out with quantum mechanical measurements (only); no explicit unitary transformations need be executed. There is a geometric requirement: “equiangularity” for not leaking quantum information. This leads to a search for large families of equiangular subspaces The Octonions allow us to construct, in a sense, the largest possible family. (Joint work with Shokrian Zini and Wang.) (A reception will follow the lecture at 6 pm in the Buttrick Hall Lobby.)

https://wp0.vanderbilt.edu/math/2019/05/seventeenth-ncgoa-spring-institute-and-34th-annual-shanks-lecture-may-3-9/
Fri, 03 May 2019 15:00:05 +0000https://wp0.vanderbilt.edu/math/?p=8628
The topic of the Seventeenth Annual Spring Institute on Noncommutative Geometry and Operator Algebras is “Algebra and Geometry Quantized and Quantified.” The conference will focus on common themes and recent developments in topology, quantum algebra, topological condensed matter physics, subfactor theory, and quantum information theory. NCGOA 2019 will be held in conjunction with the 34th Shanks Lecture, delivered by Fields Medalist Michael Freedman (Microsoft Research). More information is available on the conference website.

https://wp0.vanderbilt.edu/math/2019/04/plane-graphs-with-maximum-degree-7-and-no-adjacent-triangles-are-entirely-10-colorable/
Mon, 22 Apr 2019 20:10:41 +0000https://wp0.vanderbilt.edu/math/?p=8988Let G be a plane graph with maximum degree Delta. If all vertices, edges, and faces of G can be colored with k colors so that any two adjacent or incident elements have distinct colors, then G is said to be entirely k-colorable. In 2011, Wang and Zhu asked if every simple plane graph except the complete graph on 4 vertices is entirely (Delta+3)-colorable. In 2012, Wang, Mao, and Miao answered in the affirmative for simple plane graphs with maximum degree at least 8. We show that every plane multigraph with Delta=7, no loops, no 2-faces, and no 3-faces sharing an edge is entirely (Delta+3)-colorable. This proof uses the discharging technique to show that a minimum counterexample does not exist. (Joint work with Axel Brandt, Michael Ferrara, Stephen Hartke, and Sarah Loeb)
]]>8988On the Linear Forced Euler and Navier-Stokes Equations: Damping and Modified Scattering
https://wp0.vanderbilt.edu/math/2019/04/talk-title-tba-279/
Fri, 19 Apr 2019 22:10:08 +0000https://wp0.vanderbilt.edu/math/?p=8685We study the long-time asymptotic behavior of the linearized Euler and nonlinear Navier-Stokes equations close to Couette flow. As a main result we show that suitable forcing breaks asymptotic stability results at the level of the vorticity, but that solutions never the less exhibit convergence of the velocity field. Thus, here linear inviscid damping persists despite instability of the vorticity equations.
