About János
Bolyai
János Bolyai (15 December 1802-27 January 1860)
was born in Kolozsvár, Transylvania, at that time a Hungarian Grand
Duchy ruled by the Hapsburgs, and died in Marosvásárhely,
Transylvania. (Both towns belong to Romania now, and their names are Cluj-Napoca
and Târgu Mures, respectively.) János Bolyai, the son of Farkas
Bolyai, the famous professor of mathematics, physics and chemistry at the
Reformed College in Marosvásárhely, as a teenager set himself
to resolve the 2000 year old geometry problem, intensively researched also
by his father: to prove Euclid's fifth, the so called parallel postulate
from Euclid's others. After he had recognized the impossibility of this
task, he developed absolute geometry that is independent of the fifth postulate
and also hyperbolic geometry where this postulate is negated. He was only
21 years old when he reported his finding to his father: "I have discovered
things so wonderful that I was astounded... out of nothing I have created
a new, different world." Bolyai also developed a rigorous geometric concept
of complex numbers as ordered pairs of real numbers. Although he never
published more than the 26 page Appendix, mainly because he was unable
to gain recognition for his work, he left more than 14.000 pages of manuscript
of mathematical work when he died. Quite recently these have been thoroughly
researched with surprising success: mathematical gems have been found,
mainly results in number theory which were new in Bolyai's time.

Invitation
In 2002 we celebrate the bicentennial anniversary of the
birth of János Bolyai, the genius geometer, one of the creators
of hyperbolic geometry. In remembrance of his brilliant mind a Conference
on Hyperbolic Geometry will be held in the capital of Hungary, Budapest
from July 8th to 12th, 2002. The Conference is intended to highlight the
historical significance of the invention of hyperbolic geometry and to
present new ideas and developments related to hyperbolic geometry.

GENERAL INFORMATION
Host
city
Budapest,
the capital of Hungary, is situated in the heart of Central Europe, on
both sides of the Danube (Duna) River. On the right bank stands the hilly
and wooded Buda and on the left bank, on the plain, Pest. Biased locals
and unbiased foreign visitors hold the view that Budapest is one of the
finest situated cities in the world. Budapest is also the center of cultural
life in Hungary. It is the perfect place not only for tourists, but also
for foreign visitors attending conferences, for the city has something
to offer everyone with a few hours to spend after work or between meetings.
After visiting one of the many famous museums or historical buildings,
visitors can enjoy strolling in the downtown, along the Duna Corso or on
the Margit Island, stopping to relax in a pleasant coffee-house, a small
romantic restaurant or a cosy tavern. Evenings can be spent enjoying the
summer entertainment in a night spot, or in one of the open-air theatres
or concert halls of the city listening to the music of Bartók, Kodály
or Liszt, or perhaps enjoying a folklore performance. Those in search of
active recreation can visit Budapest’s famous baths and swimming pools.
Budapest named “the pearl of the
Danube” or “little Paris”, is definitely the city you won’t be disappointed
in, and it is just ascertain that if you come, there will be one more person
falling in love with it.

Venue
The neo-renaissance building of the Hungarian
Academy of Sciences (H-1051 Budapest, Roosevelt ter 9.) is built right on the Danube bank, in the heart
of the city. It is one of Budapest's most popular sites for scientific assemblies and conferences.
The building of the Academy can easily be reached by
public transport. The downtown area is within walking distance.

Visas
Visitors
from European countries (except Albania, Belarus, Bosnia, Moldova, Macedonia,
Russia and Turkey) are not required visas.

or in the course of travel to or from the meeting site. It is, therefore,

Arrival
in Budapest - transfer from the airport & railway
Most
participants will arrive at the Budapest Ferihegy
Airport. The simplest means of transportation to any place in Budapest
is via minibuses. This door-to-door Airport Minibus Service is reasonably
priced (approx. EUR 8) and is much more reliable than taxis.
A Railbus Service operates from
the three major railway stations, with approximately the same conditions
as the Airport Minibus.
