In science:

More precisely, the bounded derived category Db (mod-B ) of finitely generated B -modules, as wel l as the unbounded derived category D(Mod-B ) of al l B -modules, are simple in the sense that they do not admit nontrivial recol lements by derived categories of the same type.
Blocks of group algebras are derived simple
We focus on (bounded or unbounded) derived categories of finite-dimensional algebras. A derived category is said to be simple if it is nonzero and it is not the middle term of a nontrivial recollement of derived categories.
Blocks of group algebras are derived simple
These symmetries allow the effective theory to be written in terms of Fmn only, and as the result, the Lagrangian can be ordered in powers of derivatives of the photon field. A derivative translates int o the momentum, or energy, and hence the derivative expansion translates into the expansion in energy.

The where H = −∇α [N (δα covariant derivative of uα appears in the action so, although the matter is a scalar field, the aether part of E α β has derivatives of order two on gαβ and three on T , while H has derivatives of one higher order on each field variable.
Initial value constraints with tensor matter
It is not until the gauge x0 = T is chosen that the time derivative order of the theory drops to two: the field variable T disappears from the equations, and the derivative orders of E α β and H remain two and three respectively, but the third derivative in the H field equation is always in a spatial direction.
