Conditions on weights w0w_0 and wkw_k are given for the kk-th order Hardy inequality (01u(t)qw0(t)dt1/qc(01u(k)(t)pwk(t)dt)1/p(\int^1_0 |u(t)|^q w_0(t)dt^{1/q} ≤ c(\int^1_0 |u^{(k)}(t)|^p w_k(t) dt)^{1/p} to hold for two special classes of functions uu satisfying 2k2k and k+1k + 1 boundary conditions, respectively. The conditions are sufficient and partially also necessary. For one class, a hypothesis is formulated describing necessary and sufficient conditions on w0w_0 and wkw_k.
