This scientific report attempts to present as completely as possible the Laboratory's activities since 1994. The first part describes the administrative and financial aspects of the Laboratory. The second part describes the research activities, which follow the subdivision of the Laboratory into departments, which in turn break down into research groups. For each research group, we list its members and give a general presentation, after which comes a description of its research themes, perspectives, international relations, collaborations, contracts, and a brief description of a few representative initiatives. Publications are listed for each group, following the request of our Scientific Committee.
Publications involving more than one research group appear more than once.
We conclude this introduction by expressing the hopes that this report reproduces as faithfully as possible the activities of the LRI since 1994, and that the reader will find among its pages the information he or she is seeking. It is an ambitious and challenging task to mobilize 190 researchers and to coax them to provide information in a timely manner, as are aware all those who participated in the elaboration of this document. May they be warmly thanked for their work.
