ICOR'97 INTERNATIONAL CONFERENCE ON THE THEORY OF RADICALS AND RINGS SECOND (AND FINAL) ANNOUNCEMENT CALL FOR PAPERS AND REGISTRATION FORM The sixth conference in the tri-annual series on the Theory of Radicals and Rings will be held at the University of Port Elizabeth (Port Elizabeth, South Africa) during the week 7-11 July 1997. Arrivals and early registration should be on Sunday 6 July. The scientific programme will start on the Monday and should conclude on the Friday in the afternoon. SITE AND VENUES The University of Port Elizabeth (also called the Campus by the Sea) is located on the southern outskirts of city in the suburb Summerstrand. You may read more about the university on the Internet, http://www.upe.ac.za Port Elizabeth (PE) is the fifth largest city in the country with about 1 million people in its metropolitan area. It is just more than 1000 km south of Johannesburg and 800 km east of Cape Town. There are sufficiently many flights by various carriers between PE and these two cities. Daily bus and train service between these cities are also available. On arrival in PE by plane, bus or train (or boat), participants will be met and transported to their place of accommodation. If you intend to arrive by car, please indicate as such on your registration form and you will be provided with directions to the campus before your arrival. The conference office on the campus where registration will take place on the Sunday is in the foyer of Veritas Annex (this is the student hostel on the campus where participants will stay) and on the Monday it is in room 07-02-25. The format of all room numbers on the campus is: building number -level number -room number. Thus, the conference office is in building 7 (also called the Mathematics and Psychology Building), on the second floor, room number 25. All lectures, as well as the opening of the conference, will be in 05-OG-05 (building 05 is also called the SANLAM Building). LANGUAGE The conference language is English. Please note that South Africa has 11 official languages of which English is one and will suffice in most instances. VISA REQUIREMENTS AND INOCULATIONS Please check with your travel agent what your visa and inoculation requirements for South Africa will be. If you need a formal letter of invitation to the conference for your visa application, it will be provided on request. People intending to visit the Kruger National Park should take precautions against malaria. CURRENCY The SA currency is the Rand (denoted by R) which consits of 100 cents. The present exchange rate is : 1 US dollar is R4-60. Banks accept all major traveller's cheques. The major credit cards (Visa, Mastercard and Diners card) are widely accepted by hotels, shops, etc. There is a bank (Volkskas Bank) on the campus where money can be exchanged. The banking hours are Monday to Friday 09:00-14:00. CLIMATE IN JULY July is in the middle of our winter. Being a coastal city, the weather can change very quickly varying from hot and sunny to cold, windy and wet. Some statistics for the month of July during the last 20 years are (temperatures are in degrees Celsius): Ave daily temp 14, ave minimum temp 9 and the ave maximum temp 19. The lowest and highest temperatures recorded are -0,3 and 33 respectively. On average there are 7 hours of sunshine per day, 4-5 days with more than 1mm of rain and the average rainfall for the month is 44mm. There is no central heating on the campus, in fact central heating anywhere in PE is highly exceptional. You are advised to bring warm clothing and a raincoat and/or an umbrella. SCIENTIFIC PROGRAMME There will be five invited main talks of 50 min each by: GF Birkenmeier (Lafayette): Essential covers of radical classes and torsion classes; E Jespers (St John's): Noetherian semigroup algebras; K Kaarli (Tartu): Radicals of nonzero-symmetric near-rings; J van den Berg (Pietermaritzburg): Torsion preradicals - a tool for studying rings, and R Wiegandt (Budapest): Rings decisive in radical theory. ICOR97 is a very special meeting as one of our distinguished participants celebrates his 65th birthday in September. He was one of the founders of this series of conferences and is one of the few people who has attended all these conferences since the first in Eger (1982). I am refering, of course, to Prof Richard Wiegandt, whose contributions to the general radical theory not only popularised this subject, but also highlighted the strength of the techniques of radical theory outside the traditional algebraic fields. As all of his many co-authors can testify, he has been and still is, the roving ambassador par excellence for general radical theory. As a tribute to him for his contributions to this field, R. Mlitz (Vienna) will give a 50 min overview of Wiegandt's work. Participants are invited to contribute 20 minute talks. It is not anticipated that parallel sessions will be required. Lecturers are encouraged to use the blackboards in the lecture hall. An overhead projector will be available - please supply your own transparencies and pens. Only on arrival will you be provided with a programme - be prepared to give your talk on the first day. ABSTRACTS Please provide the organizers with a typed abstract of your talk, not exceeding one page. Preferably we would like to receive it together with your registration form, but if this is not possible, not later than 31 May. PROCEEDINGS The proceedings of the conference will be published as a special issue of Quaestiones Mathematicae, the journal of the South African Mathematical Society. Submissions will be subjected to the usual strict refereeing procedures of this journal. Contributors should submit their manuscripts to one of the organizers at the conference. If this is not possible, the firm deadline for later submissions is 30 September 1997. ACCOMMODATION Accommodation for the conference is in a student hostel, Veritas Annex, on the campus. All rooms are double, but also available for single occupancy (subject to availability) at the same price, with common bathrooms (separate for the different sexes though). The rooms are basic and you should provide your own towels. The price per person, including breakfast, is R65-00 per day. We will not have any lunch or dinner facilities available at the hostel. You will have to pay a small deposit for your room key which will be refunded on the return of the key. A deposit of US dollars 20 per person for confirmation of your hostel room is required with your registration form. The balance is payable on arrival (in Rands). There are two alternative options for accommodation: We have made reservations at a three star hotel (Summerstrand Inn) close to the campus (2 km) at reduced rates. These rooms have private bathroom, TV and airconditioning. The prices are: R240 for a single room and R300 for a double room per day, breakfast included. Several Bed and Breakfast rooms are available at private houses in the Summerstrand area (2-3 km from the campus). Prices for these vary between R100-R180 for a single room and R150-R240 for a double room per day, breakfast included. Your accommodation requirements must be indicated on your registration form, the organizers will make the necessary reservations (but you are responsible for settling the bill).

NB NB NB NB NB NB NB NB NB NB NB NB NB NB NB NB NB NB NB NB Because of this event, flights to and from Port Elizabeth during the first two weeks of July are booked to their capacity. You are advised to make early bookings for flights to and from Port Elizabeth. 4. Many delegates to ICOR97 will also attend the near-ring conference in Stellenbosch. With this in mind we have made arrangements with a local touring company to make a sightseeing tour from PE, along the beautiful Garden Route and Oudshoorn (to visit an ostrich farm) to Stellenbosch where the tour ends. Delegates not wanting to go to the near- ring conference may also use this opportunity to get to Cape Town. Cape Town airport is located between Cape Town and Stellenbosch (Stellenbosch is about 30 km from the Cape Town airport which in turn is about 22 km to the centre of Cape Town). The price is US dollars 320 and includes all costs (travel by bus, hotels, meals, entrance fees, etc). Please note that the price may vary slightly as it depends on the number of people participating as well as single room supplements. A deposit of US dollars 40 per person must be paid before 30 April 1997 together with your registration fee. The tour will leave from Port Elizabeth on Friday at about 16:00 and arrive in Stellenbosch on Sunday at about 18:00.
