This paper considers Hardy-Lieb-Thirring inequalities for higher order differential operators. A result for general fourth-order operators on the half-line is developed, and the trace inequality tr((-Delta)(2)-C(d,2)(HR)1/vertical bar x vertical bar(4)-V(x))(-)(gamma)<= C-gamma integral V-Rd(x)(+)(gamma+d/4)dx, gamma >= 1 - d/4, where C-d,2(HR) the sharp constant in the Hardy-Rellich inequality and where C-gamma > 0 is independent of V. is proved for dimensions d = 1, 3. As a corollary of this inequality, a Sobolev-type inequality is obtained.
