FINAL ANNOUNCEMENT The 13th Summer Conference on General Topology and its Applications June 24-27, 1998 Universidad Nacional Autonoma de Mexico, Mexico City This is the final announcement for the Conference and is sent only to those who have registered. Only new information and that needed for arrival and registration is included here. A list of registered participants and a list of talks is included at the end of this message. Please note the new information contained in most of the sections below. ARRIVAL If you are arriving at Mexico City airport between 2pm and 10pm on Monday 22nd or between 2pm and 8pm on Tuesday 23rd, watch for a person carrying a "TOPOLOGY 98" sign just outside the customs area of the international arrivals building (this area is often very crowded), who will direct you to a shuttle-bus for the hotel. We cannot give exact times for these shuttles (to the Hotel Calinda Geneve only) because of the possibility of traffic hold-ups, but there should be one leaving about every hour. If you do not happen to coincide with one of the airport shuttles, you may reach the hotel from the airport by taxi - about US$9.00. Tickets for licensed airport taxis must be bought inside the airport buildings and we recommend that you do not use the pirate taxis which are sometimes plying for hire outside. The Hotel Headquarters of the conference is Hotel Calinda Geneve Calle Londres #130, Colonia Juarez 06600 Mexico D.F. The hotel is situated in the centre of the tourist district in Mexico City (the Zona Rosa). Manuel Sanchis and Javier Trigos-Arrieta, members of the Local Organizing Committee will be staying at the Hotel Calinda for the duration of the conference and can be contacted there outside conference hours if you need any help. PLEASE ADVISE US IF YOU HAVE NOT YET RECEIVED AN E-MAIL CONFIRMATION OF YOUR HOTEL RESERVATION TELEPHONES An English speaking operator will be available from 9am to 5pm each day of the conference (i.e. 24th to 27th) at 52-5-622-4866 and 52-5-622-4867 where 52 is the code for Mexico, 5 the code for Mexico City. When in Mexico City you need only dial the final seven digits. Richard Wilson can be reached for emergencies at all times between June 22 and June 28 at the cellular phone 52-5-471-5764 from outside Mexico or 905-471-5764 from Mexico City Guests at the Hotel Calinda Geneve may be reached at 52-5-211-0071 There are a number of public telephones in the area of the Faculty of Sciences and these will be prominently indicated. All telephones require a $30.00 (thirty pesos) telephone card which will be on sale at the registration desk. International calls can be made from any phone. ************************************** LUNCHES Lunches will be served at the Ignacio Chavez Seminar Centre in the Botanical Garden of the National University each day at 1.50pm at a cost of US$5.00 per day. Transportation will be provided from the Faculty of Science, leaving at 1.40pm. Since we must let our caterers know the number taking lunch, these tickets will only be available for purchase until 6pm on Wednesday. If you intend to arrive after this time and wish to buy the lunch tickets for succeeding days, please let us know in advance by e-mail. The Botanical Garden has a unique collection of cacti, agaves and other succulents, containing species from all over Mexico. There is also a conservation area containing vegetation native to the lava-bed on which the University is built. CLIMATE Mexico and Central America have had one of the longest and most severe dry seasons this century (presumably due to the phenomenon known as El Nin~o) - in Mexico City it rained only twice between December and the end of May. The excessive dryness was the cause of a large number of forest fires, some deliberately set others accidental, which left a pall of smoke from Nicaragua to Texas. However, the anticyclone which had remained more or less stationary over Mexico for months weakened about two weeks ago and the resulting low-pressure systems finally brought rain to central Mexico on June 2nd and the fires in this region are now extinguished. With the rain, particulate pollution has dropped and should continue dropping with the demise of the fires, while cloudy, rainy conditions are not conducive to ozone production (which is the main contaminant in the atmosphere of Mexico City). The medium term forecast for June suggests that while temperatures will be somewhat above normal, with maxima of about 28C-30C (82-86F) and minima of about 15C (59F), the afternoon rains should continue and pollution levels should be within reasonable bounds. An umbrella or light rain gear might come in useful. HEALTH Mexico City lies at an altitude of 2300 metres (7,300 feet) and a very small percentage of people suffer some altitude sickness on arrival. In any case, do not attempt to do strenuous physical exercise until you are acclimatized. If the symptoms persist, then you should consult a doctor. We also recommend that you do not buy or consume food or drink in the street; however, the water and food served in the Hotel Calinda Geneve and the surrounding restaurants can be considered perfectly safe. Changes of diet (and a lot of Mexican food is quite spicy, generally much more so than the food served in so-called Mexican restaurants around the world) can cause slight intestinal and gastric problems and may not be due to any specific infection, but if the symptoms persist or are severe, then you might wish to consult a doctor. Please ask at the registration desk if you feel you require a physician. ************************************* INVITED TALKS A. V. Arhangel'skii (Ohio and Moscow State Universities), On linearly Lindelof spaces. A. Bella (Universita de Catania), Pseudoradial and related spaces. A. Garcia-Maynez (UNAM), A panorama of quasi-uniform spaces. A. Illanes (UNAM), Means on continua. R. D. Kopperman (City College, CUNY), Asymmetry - why and how to deal with it. K. Kunen (University of Wisconsin), On the Bohr topology R. McCoy (Virginia Polytechnic and State University), Spaces of semi- continuous forms. T. Nogura (Ehime University), Selections for Vietoris-like hyperspace topologies. All of these talks will take place in the Auditorium of the Library of the Faculty of Science. The SET-THEORETIC TOPOLOGY workshop on the topic of "HFC- and HFD-type spaces" directed by I. Juhasz (Hungarian Academy of Sciences) will take place in the Auditorium. The workshop on TOPOLOGICAL GROUPS directed by M. Tkachenko (Universidad Autonoma Metropolitana) will be in Lecture Room 2. All rooms are equipped with overhead projectors and blackboards; however, the blackboards in the Auditorium, where one of the sessions on Set-theoretic topology will be held and Lecture Room 2, where the session on Topological Algebraic Structures will take place are portable, and in these rooms the use of a projector is recommended. PLEASE ADVISE US IMMEDIATELY IF YOUR TALK DOES NOT APPEAR IN THE LIST AT THE END OF THIS ANNOUNCEMENT Articles for the poster session (maximum 10 pages) can be delivered to the registration desk at the National University after 9.00am on Wednesday, 24th June. ************************************** REGISTRATION The registration fee is US$95.00 which includes a copy of the proceedings of the conference (which will be published in the series Topology Proceedings), conference material, coffee breaks and the welcome reception on Tuesday June 23rd. Students are exempted from paying the registration fee and will therefore not receive a copy of the conference proceedings. The fee for accompanying persons who wish to take part in the social and cultural activities during the conference and the tour on Sunday 28th is US$40.00. Unfortunately, because of Mexican financial laws we are not able to accept credit cards for the payment of the registration fee, which can be paid at the time of registration in cash or by traveller's cheques in U.S. dollars or in Mexican pesos. Conference registration will take place at the Hotel Calinda from 3pm until 8pm on Tuesday 23rd June and from 10am until 5pm at the Library of the Faculty of Science each day of the conference (24th to 27th). WELCOME PARTY Will begin at 8pm on June 23rd at the Hotel Calinda Geneve. ************************************************************************ ************************************************************************ Any other queries should be addressed to: Richard G.
