TheSéminairehasnowanewwebsiteattheURL http://portail.mathdoc.fr/SemProba/ ThiswebsiteishostedbytheCelluleMathDocfundedbothbytheCNRSandthe UniversitéJosephFourierinGrenoble,France.WethanktheteamoftheInstitutde RechercheMathématiquesAvancées(IRMA)inStrasbourgforthemaintenanceof theformerwebsite. With the new web site also comes a new multicriteria research tool which im- proves the previous one. This tool has been developped by the Cellule MathDoc (LaurentGuillopé, Elizabeth Cherhal and Claude Goutorbe). The enormouswork of indexing and commenting was started by Paul-André Meyer in 1995 with the helpofothereditors,withanimportantcontributionfromMichelÉmery(whoper- formed the supervision of all the work) and Marc Yor. The database covers now thecontentsofvolumesItoXL.We expecttocompletetheworksooninorderto providesomeeasywaytoexploitfullythecontentoftheSéminaire. We remindyouthattheCellule MathDoc also hostsdigitizedarticlesofmany scientific journalswithin the NUMDAM project. All the articles of the Seminaire fromVolumeI in 1967to VolumeXXXVI in 2002are freelyaccessible fromthis website http://www.numdam.org/numdam-bin/feuilleter?j=SPS Finally, the Rédaction of the Séminaire is modified: Christophe Stricker and Michel Émery retired from our team after Séminaire XLII was completed. Both contributed early and continuously as authors and accepted to invest energy and timeasRédacteurs.MichelÉmerywasamemberoftheboardsincevolumeXXIX. v vi Preface Duringalltheseyears,theSéminairebenefitedfromhisdemandingqualityrequire- ments, be it on mathematics and on style. His meticulous reading of articles was sometimessupplementedbyarewritingsuggestingnotablyelegantphrasesinstead ofbasicEnglish. Whilepreparingthisvolume,weheardthesadnewsthatLesterDubins,professor emeritusatBerkeleyUniversity,passedaway.Fromtheearlydays,severaltalentu- ous mathematiciansfrom variouscountrieshave contributedto the Séminaire and Dubinswasoneofthem.
