Douglas W. Oardrization is vertical; .) the outline and the implementation of a vector ABP method for horizontal polarization; .) the application of both methods to the inversion of experimental data. Since general conditions for the well posedness of ABP methods are still unknown, the main related open problems a

Hermann Kroll,Christin Katharina Kreutz,Mirjam Cuper,Bill Matthias Thang,Wolf-Tilo Balkegroup . The action of . admits a matrix coordinatization by transvections. In terms of projective geometry, the longitudinal dilations jointly with the transvections of the .-action generate the group of homologies. The tomographic slices, frequency selected by the MRI scanner system, are identified

Tove Faber Frandsen,Jeppe Nicolaisenm of finding the potential that underlies a given spectral function also solves the problem of finding the potential that underlies a given S matrix. Once the Wiener-Hopf factorization problem has been solved and the Jost function has been constructed from the S matrix, the spectral function is know

artly technical, only a certain class of forces may be admitted. For example, in a scattering problem the potential function in the Schrodinger equation has to tend to zero at infinity, and the manner in which it is required to do so is usually dictated by technical considerations. We shall call . t
