✦ Synopsis

Real and imaginary part of the self energy and the density of states are calculated in second order parhaily self consistent Green's functmn expansion. There appear upper and lower Hubbard bands and correlation states at the chemical potential.

We determine theoretically the density of electron off-resonant states in a one-atom constriction with weak coupling between the atom at the nanoconstriction (nanowire) and the corresponding leads by considering the conductance (which is found to be low) through the wire whose insulating behavior is

The ground states of small clusters are studied within a simplified model for the two-dimensional CuO2 plane, in which doped holes on oxygen p orbitals couple with localized Cu spins. Three cases are found where the ground state has different symmetry from each other: (i) strong ferromagnetic coupli

## Abstract We show the unique global existence of energy class solutions for the Falk model system of shape memory alloys under the general non‐linearity as well as considered in Aiki (__Math. Meth. Appl. Sci.__ 2000; **23**: 299). Our main tools of the proofs are the Strichartz type estimate for
