symbolic solution of ODE


Hello,

I like to solve the ODE
DSolve[w''''[z] - 2*t*w''[z] + k*w[z] == 0, w[z], z]
by imposing the condition "t^2 < k" on constants in the eqn.In fact, solution 
of this homogenous ODE is known, but I want to see the result of mathematica 
to use in a complex eqn. Thank you.

VV
