ThisvolumeoftheLectureNotesinComputerScienceseriescontainsthep- ceedings of the Second Conference on Numerical Analysis and Applications, which was held at the University of Rousse, Bulgaria, June 11-15,2000. The conferencewasorganizedbytheDepartmentofNumericalAnalysisandStat- ticsattheUniversityofRoussewithsupportfromtheUniversityofSouthern Mississippi, Hattiesburg. The conference was co-sponsored by SIAM (Society for Industrial and Applied Mathematics) and ILAS (International Linear - gebra Society). The o?cial sponsors of the conference were Fujitsu America, Inc. ,Hewlett-PackardGmbH,andSunMicrosystems. Wewouldliketogiveour sincerethankstoallsponsorsandco-sponsorsforthetimelysupport. The second conference continued the tradition of the ?rst one (1996 in Rousse) as a forum, where scientists from leading research groups from the "East" and "West" are provided with the opportunity to meet and exchange ideasandestablishresearchcooperation.
