In this talk, I will review recent progress in understanding the
complex multi-scale plasma physics of neutron star magnetospheres
through the lens of first-principles particle-in-cell simulations.
I will highlight pair production discharges near...
I will discuss recent progress on approximating the metric
traveling salesperson problem, focusing on a line of work beginning
in 2011 that studies the behavior of the max entropy algorithm.
This algorithm is a randomized variant of the beautiful...
The TTbar deformation is a holographic theory describing
holography a finite distance in the bulk. If this
theory can be UV completed, it could be a model of nonperturbative
bulk quantum gravity. However, it seems to be a non-unitary
theory, as...
In the search for possible blow-up of the incompressible
Navier-Stokes equations, there has been much recent attention on
the class of axisymmetric solutions with swirl. Several interesting
structures of this system have led to regularity criteria...
An old open question in symplectic topology is whether all
normalized capacities coincide on convex bounded domains in the
standard symplectic vector space. I will discuss this question for
domains which are close to the Euclidean ball and its...
Many modern techniques to analyze global planetary signals, from
satellite gravity and the geoid, to magnetic fields, to the making
of seismological models, heavily rely on a global function basis -
the spherical harmonics. When the available data...
The astral sciences and early cultures: why do we study
them, and how do we share our interest with the public?Alexander Jones (ISAW, NYU) in conversation with Sonja
Brentjes (IAS, MPIWG)
Alexander Jones will present a brief survey on his...
I will present a new theory of motivic cohomology for general
(qcqs) schemes. It is related to non-connective algebraic K-theory
via an Atiyah-Hirzebruch spectral sequence. In particular, it is
non-A1
-invariant in general, but it recovers classical...
Consider the process where a signal propagates downward an
infinite rooted tree. On every edge some independent noise is
applied to the signal. The reconstruction problem asks whether it
is possible to reconstruct the original signal given...
The problem of control of large multi-agent systems, such as
vehicular traffic, poses many challenges both for the development
of mathematical models and their analysis and the application to
real systems. First, we discuss how conservation laws can...
