The journal aims to combine theoretical and mathematical papers on inverse problems with numerical and practical approaches to their solution. The main audience is pure and applied mathematicians and physicists, but the journal will also have more specialized appeal to workers in geophysics, optics, radar, acoustics, communication theory, signal processing and medical imaging. All inverse problems, inverse methods and data inversion methods are within the scope of the journal, including applications to tomography, systems identification, nondestructive evaluation and nonlinear evolution equations. The emphasis is on publishing original contributions to methods of solving mathematical, physical and applied problems. Because of the broad scope of the journal, authors should provide sufficient introductory material to appeal to a wider readership.
