Proceedings of the 7th Annual Conference of Doctoral Students - WDS'98

(Prague, 9th June - 12th June, 1998)
Edited by J. Šafránková , MATFYZPRESS, Prague, 1998, ISBN 80-85863-29-4


Three parts of the Proceedings you are holding in your hands are composed of the contributions which have been presented by students and teachers during the 7th Annual Conference of Students (Week of Doctoral Students, WDS'98) which was held in Prague, Faculty of Mathematics and Physics, Charles University from June 9 to June 12, 1998. The international meeting was divided into the different symposia in accordance with their topics and consisted of both invited lectures of professors and shorter contributions, which were presented as oral contributions or posters by doctoral students. The total number of lectures and posters was 170; 74 of them being submitted for publication in the Proceedings. This number is rather high and thus the Proceedings are divided into three volumes. Part I presents the contribution on Mathematics, Informatics and Didactics (25 contributions). The contributions from the field of Physics of Plasmas and Ionized Media are the main topic of Part II, (because 32 contributions have been submitted from this symposium). Part III consists of contributions from all other symposia on Physics (17 contributions).

All contributions in these volumes have been refereed by one experts. We would like to thank all the referees for their fruitful comments, which will make these student articles easier to read and more informative for the scientific community. We gratefully acknowledge the help of M. Králíková in editing the manuscripts.

The Proceedings from previous years were published as preprints of Faculty of Mathematics and Physics but the present Proceedings are an official publication of the MATFYZPRESS company and they are internationally registered under the ISBN number. I believe that this registration would make the reference to the articles contained in the Proceedings easier.

Judge for yourself, dear reader, if our attempt to present the results, not only those of our students but also of many other colleagues from abroad, has been successful. In the same way, we leave to your opinion the assessment of the scientific level of the contributions. However, it should be noted here that the Proceedings contain the contributions of students who have just started their postgraduate study as well as contributions of students who are about to finish their degree. We could have ordered the contributions in accordance with this criterion but we chose to arrange the papers according to their topic for the sake of easier reference.

Finally, I would like to express my thanks to all speakers and other participants for helping us to keep a fruitful and friendly atmosphere during the whole meeting and, last but not least, to the Headquarters of our Faculty for their support which allowed us not only to invite the foreign participants but also to issue the present volumes of Proceedings.

Pleasant reading, Jana Šafránková
