β¦ Synopsis
We calculate the IΒ±V characteristic of a tunnel junction containing resonant centers in the barrier distributed over a finite energy band and having an arbitrary location within the barrier. The onsite Coulomb interaction, U, between two electrons of opposite spin causes the IΒ±V characteristic to show some peculiar features when eV 9 U. The effect of the variation of the energy bandwidth and position of the impurity levels on IΒ±V characteristics is also investigated.

7'he running solutions and I-V characteristic of an extended Josephson junction in a state near the ohmic regime are calculated by a perturbation method. Both the voltage-driven and current-driven cases are considered and the convergence of the perturbation procedure is proved. An integral represent
