Tóm tắt

It is shown that at equilibrium certain matrices associated to the one-dimensional many-body problems with the pair potentialsV 1(x)=−log∣sinx∣ andV 2(x)=1/sin2 x have a very simple structure. These matrices are those that characterize the small oscillations of these systems around their equilibrium configurations, and, for the second system, the Lax matrices that demonstrate its integrability.
