This journal aims to present original articles on the theory, numerics and applications of inverse and ill-posed problems. These inverse and ill-posed problems arise in mathematical physics and mathematical analysis, geophysics, acoustics, electrodynamics, tomography, medicine, ecology, financial mathematics etc. Articles on the construction and justification of new numerical algorithms of inverse problem solutions are also published.Issues of the Journal of Inverse and Ill-Posed Problems contain high quality papers which have an innovative approach and topical interest.The following topics are covered:Inverse problemsexistence and uniqueness theoremsstability estimatesoptimization and identification problemsnumerical methodsIll-posed problemsregularization theoryoperator equationsintegral geometryApplicationsinverse problems in geophysics, electrodynamics and acousticsinverse problems in ecologyinverse and ill-posed problems in medicinemathematical problems of tomography
