## Abstract The method of double time Green's functions is used to show that two almost magnetic impurities in a nonβmagnetic conductor could under certain circumstances stimulate one another to become magnetic. Although the theory allows the formation of both parallel and antiparallel moments on t
## Abstract The integral equations arising from the Green's formula, applied to the twoβdimensional Helmholtz equation defined in a limited domain, are considered and the presence of instabilities in their numerical solution, when a real Green's function is adopted, is pointed out. A complete stud
