seminar". As announced on https://kam.mff.cuni.cz/~dsemweb/, we will have
two speakers:
Aneta Pokorná will tell us more about paper
Kempe Equivalence Classes of Cubic Graphs Embedded on the Projective
Plane by Kenta Ozeki
and
Kathryn Nurse (visiting from Simon Fraser University) will speak about
Nowhere zero 6-flows by Paul Seymour.
Regular place&time:
Time: Thursday 9:50-12:10

Hi,
unrelated to the seminar, this looks like a great zoom-talk next Friday for
those of you interested in graph theory.
Best wishes,

Dear colleagues,
We are pleased to announce a special edition of "Graph Theory in Paris"
event to be held on zoom:
Speaker: Claude Tardif, from RMC.
Title of the talk: New counterexamples to Hedetniemi's conjecture
Time: Friday 02 December 2022, 15:00 Paris time (9:00 Toronto time)
More details, including the zoom link, at:
https://www.irif.fr/~gtp/2022Autumn.html
Note 1: Claude will take questions and, therefore, no time limit will be
posed on the talk. Moreover, we may have discussions after the talk.
Note 2: Feel free to forward this invitation to any person or group that
might be interested.
=========================================
GTP is a young series, aiming to gather together graph theorists in Paris
once or twice a year. Activities were naturally on pause. However, given
the high interest of the subject for this session, which goes far beyond
Parisian graph theorists, we decided to have this session on zoom.
*Claude will present a full resolution of Hedetniemi's conjecture in this
talk. This is an old conjecture on the chromatic number of the categorical
product of two graphs.*
We hope to resume our activities in 2023. For suggestions of speakers, or
to help us organize next events do not hesitate to write to us.
Looking forward to seeing many of you on Dec 02,
Organizers: Reza, Valia, Zhouningxin

Dear all,
1) just a reminder, this week there is no seminar, as Thursday is a state
holiday.
2) next week, we will have Aneta and graph coloring, more detailed info
will come early next week.
3) last but not least: as Christmas is approaching, we are thinking of
organizing seminar pub night
-- a dinner in some nearby restaurant for seminar attendees (and
friends).
(We have no funds to pay for this though, so everybody is on his/her
own.)
If you want to come, please vote at
https://doodle.com/meeting/participate/id/bk8jvNXd
to select the day when this will happen. (The time of start will be
around 7:30 p.m.)
Best wishes,
