SUMMARY:Math Seminar Series
DESCRIPTION:
Colloquium\n
\n
Ruixiang Zhang from IAS will be
speaking.\n
\n
The title is "Kakeya type problems
and analysis".\n
This meeting will take place
over Zoom.\n
\n
The event description is as
follows:\n
\n
Informally, Kakeya type problems
ask whether tubes with different positions and
directions can overlap a lot. One usually expects
the answer to be no in an appropriate
sense. Thanks to the uncertainty principle, such
a quantified non-overlapping theorem would
often see powerful applications in analysis
problems that have Fourier aspects. Perhaps
the most well-known Kakeya type problem is the
Kakeya conjecture. It remains widely open in
Rn(n>2) as of today. Nevertheless, in the recent
few decades people have been able to prove
new Kakeya type theorems that led to improvements
or complete solutions to analysis problems
that appeared out of reach before. I will
give an introduction to Kakeya type problems/theorems
and analysis problems that see their
applications. Potentially reporting some
recent progress joint with Du, Guo, Guth, Hickman,
Iosevich, Ou, Rogers, Wang and Wilson.\n\n
