The Birkhoff attractor is a closed invariant subset associated
with any dissipative twist map of the annulus (of dimension 2),
which was introduced by Birkhoff in 1932. We will see that it can
be generalized to higher dimensions using tools from...
The goal of these lectures is to present the fundamentals of
Simpson’s correspondence, generalizing classical Hodge theory,
between complex local systems and semistable Higgs bundles with
vanishing Chern classes on smooth projective varieties.
Tidal disruption events — where an unfortunate star is destroyed
by a previously quiescent supermassive black hole — offer a unique
probe of the low mass end of the supermassive black hole
population. Recent observational advances have lead to the...
The fields of computer science and game theory both trace their
roots to the first half of the 20th century, with the work of
Turing, von Neumann, Nash, and others. The 21st century has seen
many fruitful points of contact between these two fields...

The interstellar medium (ISM) is a turbulent, multi-phase,
magnetic environment. It is home to vastly different gas phases,
from cold, dense clouds to hot, tenuous plasma. Magnetic fields
thread this interstellar environment, helping to sculpt...
