THE NEWSLETTER OF THE MATHEMATICAL ASSOCIATION OF AMERICA VOLUME 5 NUMBER 6 NOVEMBER-DECEMBER 1985 A Visit to Vietnam Peter Hilton n early April of this year, I received a 'mysterious' phone tion of geometry, topology and algebra in the Faculty of call from Dr. Judy Ladinsky, Professor of Preventive Med Science, and by Hugh (such, he said, was his name, but I Iicine at the University of Wisconsin-Madison. It transpired suspect he used adifferent spelling!) on behalf of the Ministry that she was telephoning me, in her capacity as chairwoman (continued on page 2) of the U.S. Committee for Scientific Cooperation with Viet nam, to enquire if I would be able to visit the University of Hanoi after attending an international conference on alge braic topology in Singapore in mid-June. It was known to the Hanoi topologists, and particularly to Dr. Huynh Moi, the leader of the algebraic topology group there (who was at the time visiting the U.S. and was actually in Dr. Ladinsky's office when she made her phone call) that I would be in Singapore at the conference, and that I had made a considerable effort to get some Vietnamese topol ogists invited to that conference. (My efforts foundered, unfortunately, owing to the strained political relations between Singapore and Vietnam.) I agreed to visit Hanoi from June 21 to June 26, and learned that it would be necessary to go to Bangkok to get my visa and then fly to Hanoi from Bang kok. In fact, Bangkok is the unique airport in the non-com munist world from which one can fly directly to Hanoi, but there are only 2 flights a week in each direction! I arrived in Bangkok on Thursday, June 20, and, after some difficulties with my visa, caught a flight for Hanoi early the next morning on a Vietnamese airline. On arrival, I was met by Professor Pham, head of the sec- The January 1986 Joint Mathematics Meetings The January 1985Joint Mathematics Meetings will be held in New Orleans, Louisiana, January 7-11.

There is no doubt at all that the Vietnamese, but more especially the intellec tuals, would want far more contact with colleagues from the West. Indeed, they are starved of such contact, at first or second hand. I was told that I was only the second mathematician from the U.S. to visit Vietnam since 1975 (the other being Neal Koblitz ofthe University of Washington). A few dedicated medical scientists (Dr. Ladinsky, whose committee arranges such visits, among them) have visited Vietnam and done wonderful work there in combating disease and inculcating FOCUS (ISSN 0731-2040) is published by the Mathematical good health habits; but the overall picture is one of almost Association of America, 1529 Eighteenth Street, N.W., Wash total isolation.
