Dear colleague, it is a pleasure for us to invite you to the Spring School on Combinatorics 2008. It will be held from April 15 to April 24 in Rokytnice nad Jizerou, Czech Republic. The participants will be undergraduate and graduate students of mathematics or of computer science with some of their professors. If you want to participate, please, send us filled-in MINI-QUESTIONNAIRE appended below concerning travel, programme, accommodation, etc., not later than March 19! Please fill in and send us the questionnaire also in case that you are not a student. The main part of the scientific programme will be students' presentations of papers on combinatorics, graph theory, algorithms or other related areas. Students may also present their own research results, after an arrangement with the organizers. The presentations, following a long tradition of the Spring Schools of the Prague Combinatorial Seminar, are usually rather informal, intermixed with curious questions of those who are (not) following the presentation, and other events (pictures somehow capturing the atmosphere of the previous Spring Schools can be found webpages of the Spring School). The participants are expected to attend all the lectures. The school schedule will allow sufficient opportunities for leisure time activities (hiking, biking, etc.). Continually updated information about the Spring School will be displayed at Spring School webpages (http://kam.mff.cuni.cz/~spring). Allow us to state that in 2008 we have not a support of Spring School in the framework of an EU-Socrates programme. Thus our possibilities are somewhat limited so we would appreciate if you could cover a part of the expenses from an alternative source: we shall charge a symbolic registration fee 200 EUR towards lodging and meal expenses, bus transportation and others. This amount should be paid upon the arrival. If you are not able to provide the reimbursement let us know and we will try to help you. The registration fee is waived to students of Czech Universities. In any case we do not want to discontinue our tradition of international Spring Schools besides that we hope that in 2009 and years to come we shall have support of an EU grant. Rokytnice nad Jizerou is a small village near the border of the Czech Republic and Germany. The surrounding landscape is beautiful and in the time of the Spring School it offers opportunities for hiking and mountain biking (and may be even cross-country skiing); bike rental is in the place of the School. A special bus will be arranged for going to Rokytnice nad Jizerou on April 15 (the departure time can be discussed according to the needs of participants; a preliminary suggestion is to leave in the morning) and from Rokytnice nad Jizerou on April 24 (the arrival time to Prague will be adjusted to your demands). If you want to stay overnight in Prague before or after the Spring School, we can arrange a dormitory-style accommodation for you assuming that you fill this in your questionnaire. The costs for the Prague accommodation will be up to 40 EUR per night. The address of the hotel where you will be accommodated is: Penzion Zlata Vyhlidka Studenov 14 51244 Rokytnice nad Jizerou The Czech Republic Telephone: +420 776 383 080 If you have any questions, feel free to send them by e-mail to spring@kam.mff.cuni.cz.
