Summary
We study the uniqueness questions for the inverse problem of determining hamiltonian H(x,p)= gij (x) pi pj and a phase function w(x,t)  from the Hamilton-Jacobi equation and the initial-terminal conditions w(x, t0 ), w(x, t1). Here the unknown functions gij(x) compose a matrix inverse to that of the metric tensor. We obtain uniqueness theorems for special classes of initial-terminal conditions in the cases n =1, n=2 and in the case of a scalar n×n  matrix gij(x).
