ABSTRACT.  We consider the cubic and quintic Gross-Pitaevskii (GP) hierarchy in $d$ dimensions, 
for focusing and defocusing interactions. 
We introduce new higher order conserved energy functionals that allow us to prove 
global existence and uniqueness of solutions for defocusing 
GP hierarchies, with arbitrary initial data in the energy space. 
Moreover, we prove generalizations of the Sobolev and Gagliardo-Nirenberg inequalities 
for density matrices, which we apply to establish global existence and uniqueness 
of solutions for focusing and defocusing GP hierarchies on the $L^2$-subcritical level.
