Raytcho Lazarov is a computational mathematician of extraordinary depth and breadth whose work has had and continues to have exceptional impact on computationalandappliedmathematics.Hehasauthoredorcoauthoredmorethan 200 journal publications and 4 books spanning all major areas in computational mathematics and bridging mathematical theory and scientific computing with sciencesandengineering. RaytchoLazarovwasborninKardzhali( ),Bulgaria,onJanuary23, 1943.Hegraduatedfrom“St.AntimI”High(cid:0)S(cid:2)ch(cid:3)o(cid:4)o(cid:5)l(cid:6)in(cid:7)Z(cid:8)latograd( )and in 1961 went to Sofia University “St. Kliment Ohridski” to con(cid:9)tin(cid:7)u(cid:6)e(cid:10)(cid:11)h(cid:12)i(cid:3)s(cid:6)s(cid:4)tudies in the Department of Mathematics (industrial profile). During his first year as a collegestudent,Raytchodemonstratedhistalentformathematics,andhisdedication to study it, and he was selected to continue his education at the University of Wroclaw in Poland in 1963. In Wroclaw Raytcho was able to interact with many distinguished mathematicians from the Polish mathematical school and received first-ratemathematicaltraining. In1968RaytchoLazarovwasadmittedtothePhDprogramoftheMoscowState University. As a graduate student in Moscow, he studied and worked under the supervisionofAcademicianA.A.Samarskiiwhowasoneofthebestcontemporary computationalmathematiciansin the world. Lazarov’sthesis workwas on “Finite differenceschemesforelasticityproblemsincurvilineardomains,”amongthefirst rigorousstudiesofnumericalapproximationsofproblemsinstructuralmechanics. AfterreceivinghisPhDdegreein1972,RaytchoLazarovworkedasaresearch associate andseniorresearchassociate in theInstitute ofMathematics(IM)ofthe BulgarianAcademyofSciences(BAS)until1987.Duringthistimeheestablished himself as one of the leading experts in numerical analysis. In 1976 Raytcho Lazarov visited the Rutherford Laboratory in Didcot, UK, for one year, and this visithadnotableimpactonhisfutureresearch.Hisfocusshiftedtothetheoryand applicationsof the finite elementmethod (FEM) which remainsto be his primary fieldofresearchtothisday. Lazarov earned the degree of doctor of sciences in June 1982 with a thesis on “Error estimates of the difference schemes for some problems of mathematical physics having generalized solutions.” This thesis contained several breakthrough results, which were published in more than 10 papers and formed the basis for a research monograph that he coauthored with A. A. Samarskii and V. Makarov, Difference Schemes for Differential Equations Having Generalized Solutions, whichwaspublishedin1987. In 1986 Lazarov’s superb scientific achievements earned him the title of a professorofmathematicsattheInstituteofMathematicsoftheBulgarianAcademy ofSciences, a positionthathe continuesto hold to thisday.His leadershipability viii Preface was also recognized by his colleagues, and in 1985 he became the head of the Laboratoryon NumericalAnalysis, BAS, and a deputy-directorof the Laboratory on Parallel Algorithms and High Performance Computer Systems, BAS. In 1986 Lazarov became deputy-director of the newly established Center for Informatics andComputerTechnology(CICT)atBAS.Thiswasoneofthefirstinterdisciplinary centersworldwideformathematicalresearchonadvancedalgorithmsfortheemerg- ing parallel computer systems. He played a crucial role in hiring a cohort of the best young applied mathematicians in Bulgaria—Djidjev, Vassilevski, Margenov, Dimov, Bochev, and many more. In fact, Raytcho Lazarov’s leadership was the keyinmakingCICToneofthebestplacesforlarge-scalescientificcomputingand parallelalgorithms.In1984Raytchoinitiatedaseriesofinternationalconferences onnumericalmethodsandapplicationsinSofia,Bulgaria,whichhelpedtopublicize the results and achievements of the Bulgarian numerical analysts and to integrate themintotheinternationalcommunity. Such accomplishmentswere noticedby hiscolleaguesaroundthe world. Vidar Thome´ehelpedRaytchotogetavisitingpositionattheUniversityofWyomingin 1987.ThisturnedouttobeacriticalpointinLazarov’scareer.InWyominghemet andbefriendedRichardEwingwhoatthattimewasadirectoroftheEnhancedOil RecoveryInstitute(EORI)andtheInstituteofScientificComputation(ISC) atthe UniversityofWyoming.DuringhisstayinLaramiein1988–1992,Lazarovworked onsuperconvergenceandlocalrefinementtechniquesformixedFEmethods.During that time Raytcho initiated many collaborations and friendships with prominent mathematicians such as Jim Bramble, Joe Pasciak, Panayot Vassilevski, Junping Wang,TomRussell,YuriKuznetsov,SteveMcCormick,TomManteuffel,andOwe Axelsson. At that time Raytcho Lazarov led the developmentof algorithmsbased ontheBramble–Ewing–Pasciak–Schatz(BEPS)preconditionerandlocallyrefined mixed FE and finite-volume methods that were also implemented in the EORI proprietarycodes. The friendship and collaboration with Dick Ewing initiated another change in Raytcho’scareer, and in 1992he movedto Texas A&M University as a professor of mathematics, a position that he continues to hold now. This coincided with the establishment of the Institute of Scientific Computation (ISC) at Texas A&M underthedirectorshipofRichardEwing,whichquicklyattractedateamofworld- renowned experts in this area like J. Bramble, J. Pasciak, R. Lazarov, and, more recently, Y. Efendiev, J.-L. Guermond, G. Petrova, B. Popov, W. Bangerth, and A. Bonito. The work they did in the last 20 years on computational mathematics and its applications in flows in porous media, multiphysics problems, modeling of fluids, structures and their interactions, etc. had a significant impact on these and in other research areas. Raytcho’s pivotal role in this research is well known fromhisresultsonleast-squaresFEM;discontinuousGalerkinmethods;multigrid, multilevel,andmultiscalemethods,mixedFEM,andmorerecentlyfractionalorder partialdifferentialequations. In recognition of his achievements Raytcho Lazarov has been awarded several honorarytitlesanddegrees:the medal“St. Kl.Ohridski”with blueribbon(2003– thehighesthonorsgivenbySofiaUniversity,Bulgaria,toscientists);DoctorHonoris Preface ix Causa of Sofia University “St. Kl. Ohridski” (2006); the medal of the Institute of Mathematics, Bulgarian Academy of Sciences 2008; Pichoridis Distinguished Lectureship, University of Crete, Greece (2008); and Erasmus Mundus Visiting Scholar Award, University of Kaiserslautern (2008).Most recently he was named a recipient of the medal of the Bulgarian Academy of Sciences “Marin Drinov” withribbon(2013),whichisgiventoscholarsforoutstandingcontributionsinthe advancementofscience. DuringhiscareerLazarovhasheldvisitingpositionsandcontributedtoadvance- mentofresearchin manyinstitutionsaroundthe globe:JointInstitute forNuclear ResearchinDubna,Russia(1980);AustralianNationalUniversity,Canberra(1990); Mittag Leffler Institute of Mathematics, Stockholm, Sweden (1998); University of Linz and RICAM, Austria (2005); Fraunhofer Institute of Industrial Mathe- matics,Kaiserslautern,Germany(2006);LawrenceLivermoreNationalLaboratory (regularly from 1998 to 2010); and KAUST in Saudi Arabia (2008–2013).He is a member of the editorial board of five international journals and a number of conference proceedings, and he is also serving on the scientific committees of severalinternationalconferences.
