## Abstract Inhomogeneous magnetic fields produce artifacts in MR images including signal dropout and spatial distortion. A novel perturbative method for calculating the magnetic field to first order (error is second order) within and around nonconducting objects is presented. The perturbation para
We consider open quantum systems described by a Hamiltonian of the type H 0 + AV, where A is a small parameter. For such systems, we develop perturbative methods of solution of the corresponding Liouville-von Neumann and Schr6dinger equations, by introducing "dissipation" operators which connect con
