The Japanese Conference on Combinatorics and its Applications  (JCCA 2018)

in Sendai


May 20-24 , 2018






The slides of talks left in our computer are made open here , except for the ones the speakers do not wish to publicize.


The conference photo is ready.  See " Confernce Photo" below.

The organizers intend to post a conference report to Institute of Combinatorics and its Applications (ICA).   In order to use the conference photo in the report, we need a permission from the people in the picture.  If you are in the photo and you do not wish it to be used for the report to ICA, please contact us at jcca-office@sk.tsukuba.ac.jp by July 10, 2018.  If we do not receive a negative opinion by this date, we will use it to the report.
