The total number of participants of the congress was 502 coming from 62 countries, including the special guests and the OrganisingCommitteefromKrakowandRzeszow.Therewere12plenaryspeakers and 2 key speakers of the discussion group on applications. Totally, the congress had23sessionsspannedover4workingdays,while1daywasassignedtoexcur- sions.Thecongresswassponsoredbyindustrialpartners.Whenneeded,thePolish consulatesoverEuropeissuedfreevisasforparticipantsofthecongress. Oneofthemainfeaturesofthecongresswastheinvitationofindustrialspecial- ists, especially engineers working in industry, whose activity is related to applied mathematics(industrialmathematics)andcomputersciences.The9thInternational ISAAC Congress was an important scientific event during which mathematicians from different parts of the world had an opportunity to present new results and ideas.Itwasalsoagreatpossibilityforyoungmathematicianstocontactexpertsin avarietyoffields. TheatmosphereduringtheCongresswaswarmandfriendlyatthesessionsand atthesocialevents:banquet,excursions,footballmatchfollowedbyabarbeque.It is impossible to give the final score of the football match because too many goals werescored. The dates of the Congress, namely 5–9 August, provided for an extremely hot periodinthehistoryofKrakowthatcorrelatedwellwithhotandfruitfulscientific discussionsduringtheCongress. It is already a well-established tradition to award one or several outstanding young researchers during the ISAAC congress. The ISAAC award of the 9th In- ternationalISAACCongresswaspresentedto JassonVindas (UniversityofGhent,Belgium) v vi Preface for his outstanding results on the asymptotic behaviour of Schwartz distributions andtheirpointwisevalues. AttheISAACboardmeetingduringthecongressProfessorLuigiRodinoofthe UniversityofTurinwaselectedasthenewISAACPresident,andProfessorMichael Reissig of Freiberg University as the new Vice-President. The former president, Professor Michael Ruzhansky of Imperial College London, UK, has finished his 4-yearservice.Theelectionofthenewvice-presidentandnewrulesconcerningthe structureandfunctioningoftheinterestgroupswithinISAACcompletedthework onthenewISAACconstitutionthattookplaceintheyearbeforethecongress.The newconstitutionwasapprovedbythegeneralelectronicvotebyISAACmembers priortothecongress.FurtherinformationcanbefoundontheISAAChomepage www.mathisaac.org The ISAAC Board has decided the venue for the following 10th International ISAACCongressin2015tobetheUniversityofMacau. The plenary and key lectures given at the congress appear not here but in the independentvolume: Mityushev V., Ruzhansky M. (Eds.) Analytic Methods in Interdisciplinary Applications. SpringerProceedingsinMathematics&Statistics,Vol.116,Springer,2015. The present volume contains the texts of a selection of talks delivered at the congress.Asinthepreviousyears,someofthesessionsorinterestgroupsdecided to publish their own volumes of proceedings and are therefore excluded from the presentcollection.Theworkofthecongresswasspreadoverthefollowingsessions: • Complexvariablesandpotentialtheory, organisedbyT.Aliyev,A.Golberg,M.LanzadeCristoforis,S.Plaksa • DifferentialEquations:ComplexandFunctionalAnalyticMethods,Applications, organisedbyH.Begehr • Complex-analyticmethodsforappliedsciences, organisedbyS.V.Rogosin • CliffordandQuaternionAnalysis, organisedbyS.Bernstein,U.Kähler,I.SabadiniandF.Sommen • FixedPointTheoryandApplications, organisedbyE.Karapınar • SpacesofDifferentiableFunctionsofSeveralRealVariablesandApplications, organisedbyV.BurenkovandS.Samko • GeneralizedFunctions, organisedbyM.OberguggenbergerandS.Pilipovic´ • QualitativePropertiesofEvolutionModels, organisedbyK.Yagdjian,F.HirosawaandM.Reissig • NonlinearInfiniteDimensionalEvolutionsandControlTheorywithApplications, organisedbyI.Lasiecka,J.WebsterandG.Avalos • NonlinearPDE, organisedbyV.GeorgievandT.Ozawa • TopologicalandGeometricalMethodsofAnalysis, organisedbyA.Prykarpatskyi,Yu.ZelinskyiandK.Soltanov Preface vii • DidacticalApproachestoMathematicalThinking, organisedbyE.SwobodaandV.Mityushev • WaveletTheoryAnditsRelatedTopics, organisedbyK.FujitaandA.Morimoto • IntegralTransformsandReproducingKernels, organisedbyS.SaitohandJu.Rappoport • Pseudodifferentialoperators, organisedbyL.Rodino,J.ToftandM.W.Wong • MedicalMathematicsandComputing, organisedbyR.Gilbert,Ju.RappoportandV.Yakushev • ToeplitzOperatorsandTheirApplications, organisedbyS.GrudskyandN.Vasilevski • ApproximationTheoryandFourierAnalysis, organisedbyS.TikhonovandE.Liflyand • DifferentialandDifferenceEquationswithApplications, organisedbyL.Berezansky,J.Diblik,A.ZaferandM.Zima • AnalyticMethodsinComplexGeometry, organisedbyA.Schmitt • M-FrameConstructions, organisedbyK.Rudol,H.G.Stark,A.GrybosandD.Onchis • Applications of Queueing Theory in Modelling and Performance Evaluation of ComputerNetworks, organisedbyK.Grochla • AppliedMathematics, organisedbyS.Bosiakov • Otherscontainingothertalks, organisedbytheeditorsofthisvolume Wethanktheorganisersofallthesessionsofthecongressfortheirwork.They spent an enormous amount of time inviting participants, arranging their sessions, providing chairmen and creating a familiar and workshop-like atmosphere within their meetings.
