We would like to announce at this place, too, that Algebra Universalis intends to publish a special issue dedicated to the seventieth birthdays of George Grätzer and Tamás Schmidt. Papers intended for this issue are to be submitted electronically to the Executive Editor, Robert W. Quackenbush qbush_AT_cc_DOT_umanitoba_DOT_ca, the submission deadline is December 31, 2006.
Site
The conference will take place at the Alfréd Rényi Institute of Mathematics, Hungarian Academy of Sciences, where the two jubilees got their first employments in 1958. The Institute is located in the centre of Budapest, the address is Reáltanoda utca 13-15, close to each underground line. For a map and directions please check this page.
Side program
In the late afternoon and the evening of Thursday, 8 June, there will be a sightseeing boat tour on the Danube, followed by a banquet in the Rényi Institute.
Visa
Most of the prospective conference participants come from states whose citizens need no visa to enter Hungary. For a checking list of these countries you can consult the website of the Hungarian Ministry of Foreign Affairs.
