- We study the time and temperature dependent correlation functions for an impenetrable Bose gas with Neumann or Dirichlet boundary conditions (x1, 0) (x2, t) ±,T . We derive the Fredholm determinant formulae for the correlation functions, by means of the Bethe Ansatz. For the special case x1 = 0, we express correlation functions with Neumann boundary conditions (0, 0) (x2, t) +,T , in terms of solutions of nonlinear partial differential equations which were introduced in  as a generalization of the nonlinear Schrödinger equations. We generalize the Fredholm minor determinant formulae of ground state correlation functions (x1) (x2) ±,0 in , to the Fredholm determinant formulae for the time and temperature dependent correlation functions (x1, 0) (x2, t) ±,T , t R, T 0.
