Abstract: | For short-range oscillating potentialsV(r), such that
possesses some regularity properties we establish inequalities on the number of bound states. In particular we show that by replacingV(r) by –4(W(r))2 in the classical inequalities we get bounds for this new class of potentials. Optimal bounds are also obtained. The behaviour for large coupling constants is studied. |
