日韓数学会合同会議２０１２
平成２４年９月１７日（月）九州大学医学部百年講堂で開催された，日韓数学会合同会議２０１２に参加してきたのでその報告をしたい．当日は台風１６号の影響が心配されたが，幸いにして台風も逸れ，朝からの参加者の出だしもまずまずであった．午前は全体講演二つ，午後は代数，幾何・トポロ
ジー，解析，確率論・応用の４つのセッションに分かれ，それぞれ４つの講演が行われた．初めての日韓数学会合同会議と言うこともあり，午前の全体講演者は二人とも，日韓数学者のそれぞれの分野での関係の深さを強調していたのが印象に残った．午後からは天気が良くなったこともあり，驚く総合講演中村 玄 氏

ほどたくさんの参加者が集まった．（日本数学会事務局によると，用意していたアブストラクト集２００部はすべてはけたそうである．）やはり，多くの参加者が集まった最大の理由は，講演者の質が高かったことであろう．組織委員会の方々の努力を讃えたい．またその晩には懇親会が開かれ，事務局によると約９０名が参加し，日韓数学会の交流を深めた．
（ちなみに，台湾数学会の派遣団もこの合同会議と懇親会に参加した．）今回の合同会
議は大成功であり，今後も日韓数学会合同会議が継続する

総合講演
Jun-Muk Hwang 氏

ことを願わずにはいられない．
（政治的には色々問題を抱える東アジアではあるが，将来的には， 日本，韓国，台湾，中国数学会合同会議が理想であろうか．）最後に，地元で合同会

Opening Address
at MSJ-KMS Joint Meeting 2012
Good Morning, Ladies and Gentlemen:
It is great pleasure and honor for me to have you at the ﬁrst Joint Meeting of
the Mathematical Society of Japan and the Korean Mathematical Society.
We thank the speakers and the audience who have arrived here despite theTyphoon No. 16 approaching Fukuoka.
As you know, the recent development of mathematics in Asian countries –Korea, Taiwan, China, Vietnam and so on – is very fast and remarkable,
meaning that we need to advance research cooperation and mutual exchangeof ideas within Asia. In view of this situation, the idea of this meeting isto showcase top level mathematical achievements in Japan and Korea, andthereby help people ﬁnd chances for new joint researches and projects. As
you see in the program, one plenary talk and eight session talks are provided
by Japan and Korea, respectively. We are sure that all the talks will be ofgreat interest and high scholarly level.
The venue of the meeting is Centennial Hall of the Medical School, Kyushu
University. It is not by chance that we chose Kyushu University, Fukuoka,
as the venue of the ﬁrst Joint Meeting. There are at least two reasons.
The ﬁrst one is rather practical. Kyushu University is one of the major
universities in Japan with one of the biggest mathematics department. Thismeans that university facilities and human resources are simultaneouslyavailable. This beautiful hall and the corps of graduate students are both
indispensable for the preparation of the meeting. We are cordially gratefulto Kyushu University and its staﬀ, particularly to the local organizers teamled by Professor Miyuki Koiso.
The second reason is more symbolic. Historically, Fukuoka has been theprincipal Japanese gateway to Asian civilizations. An artifact, a gold seal,
was discovered in Fukuoka which proves that there was a contact between
Japan and Chinese Han dynasty as early as in the ﬁrst century. In the8th century, there was a guest house here for people from the continent.
Diplomats from Japan and Korea used to compose poems in Chinese, theAsian common language at the time. Even today, Fukuoka is an international city with considerable Asian population. You can taste the inﬂuencesof Asian cultures in wonderful foods of Fukuoka, which are famous not only

for fresh ﬁsh but also for their great varieties. In the evening, you will enjoy
Fukuoka’s international culinary culture.
Frankly speaking, there are some political disputes between Japan, Korea
and other Asian countries. However, we have been, are and will be neighbors. You cannot refuse this simple fact. The typhoon now hitting Japancame from Taiwan and will reach Korea tomorrow. We should rather cooperate with each other to cope with problems than ﬁghting against eachother. I should be very happy if this meeting would help mitigate politicaltensions through scholarly partnership, cooperation and frank discussions.
Fortunately, we mathematicians have our own common language, mathematics, free from prejudices and nationalistic enthusiasm. In some sense,
this meeting is just a starting point. In near future it will hopefully develop
into a joint meeting of a bigger framework, involving Taiwan, continental
China and other Asian countries as well.
Thank you for your attention.
Yoichi Miyaoka,
President of the Mathematical Society of Japan
