[K-OS] Knot Online Seminar
[K-OS] is an online research seminar which focuses on knot
theory and low-dimensional topology. It happens every
Thursdays from 14:00 to 15:00
(
CET/CEST Berlin,
Brussels, Madrid, Paris, Rome, Vienna, Warsaw, Zurich)
on
Zoom.
It is organized by
Alexandra
Kjuchukova,
Lukas
Lewark,
Louis-Hadrien
Robert and
Emmanuel
Wagner.
It benefits from logistical support from
the
CNRS, the university
of
Paris and the
university of
Regensburg.
Forthcoming Talks
19/05/2022
- Speaker: Arunima Ray (Max Planck Institute für Mathematik)
- Title: Slicing knots in definite 4-manifolds
- Abstract: I will give an overview on questions
related to slicing knots in 4-manifolds more general
than the 4-ball. Then, I will focus on the
ℂℙ2-slicing number of knots,
which is by definition the smallest integer m
such that the given knot bounds a properly embedded,
null-homologous disk
in m(ℂℙ2) minus a
ball. Specifically, I will give a lower bound on the
smooth ℂℙ2-slicing number and
an upper bound on the topological
ℂℙ2-slicing number, and
describe situations where these quantities are
large/small/distinct. The talk will be based on joint
work with Alexandra Kjuchukova, Allison Miller, and
Sumeyra Sakalli.
