Hi Binzhous, Arik,
... [puma_undergrad] introduction to topology tomorrowArik Wilbert)
http://www.freelists.org/post/puma_undergrad/introduction-to-topology-tomorrow
http://www.freelists.org/post/puma_undergrad/introduction-to-topology-tomorrowHello everyone,
This is just a quick reminder that Adrian will give an introduction to topology
in our seminar tomorrow. The focus will be on the definition of the fundamental
group and hopefully (if time permits) the Galois correspondence for covering
spaces. This will nicely complement the algebraic picture (involving field
extensions) which you learned from Nora in the lectures. In my opinion, this is
basic material that every serious student in pure math should know by the end
of his or her undergrad studies. Unfortunately, the department was not able to

http://www.freelists.org/post/puma_undergrad/interesting-ICM-talksHi everyone,
I wanted to point out two ICM2018 plenary lectures which are closely related to
the contents of our seminar.
1) Have a look at G. Williamson't talk here:
themes that we discussed in the seminar (e.g. SU(2), finite reflection groups,

http://www.freelists.org/post/puma_undergrad/more-on-knotsHello everyone,
Here are two things which are both educational and entertaining in case you get
bored over the break.
1) The Witten quotation from yesterday's email can be found here (at about 6
min into the video):

http://www.freelists.org/post/puma_undergrad/talk-7-tomorrow
http://www.freelists.org/post/puma_undergrad/talk-7-tomorrowHello everyone,
Just a quick reminder that Finn is giving a survey talk on knot theory, the
Jones polynomial and how it relates to the Hecke algebra tomorrow (Thursday) at
3:15pm in the Russell Love Theatre. In 2010, mathematical physicist Edward
Witten said Even though it is very modern, and near the frontier of
contemporary mathematics, the Jones polynomial is so simple that it could be
taught in high school without compromising very much. There are not many
frontier developments in mathematics that one would say this about. I will

basically an extended version of Tom's talk including many examples and nice
pictures (if you went to Marcy's Escher talk you might recognize the
tesselations on pp. 7-8).

http://www.freelists.org/post/puma_undergrad/talk-6-tomorrow
http://www.freelists.org/post/puma_undergrad/talk-6-tomorrowHello everyone,
I thought I would test our new email list and advertise tomorrow's talk. Tom
will go through p. 2 of Soergel's paper Kazhdan-Lusztig Polynome und eine
Kombinatorik für Kipp-Moduln and define the Kazhdan-Lusztig basis as well as
calculate some examples. At the end we should be able to understand the
statement of the Kazhdan-Lusztig positivity conjectures. In full generality,
they were only proved five years ago. Positivity hints at the existence of a
much richer, higher-dimensional (in maths we say categorified ) world of which
