✦ Synopsis

A variational approch is proposed for the approximate description of decaying states represented by Gamow functions. The method is suited to describing many-particle systems with antisymmetry. It is shown that, in combination with a generator-coordinate basis, its actual application is as feasible as an ordinary bound-state generator-coordinate calculation. Model calculations reveal that, as an approximation method, it has very favourable properties.

## Abstract A derivation of hydrodynamic equations which describe diffusion in connection with reaction processes in many‐particle systems is given on the basis of quantum kinetic theory. For this purpose kinetic equations are derived for a quantum gas with chemical reactions. Following Grad's meth

We consider subquadratic perturbations of semilinear elliptic systems which are in variational form. A unified approach to both the cooperative and noncooperative problems is presented and a condition of nonquadraticity at infinity is introduced to treat the resonant cases through minimax techniques
