Are now but operatives; War's made
Less grand than Peace,

In science:

In section 4, under some compatibility conditions between the operator A and the subspaces S and T , we define a bilateral shorted operator A/(S , T ) ∈ L(H1 , H2 ), and we study the usual properties of a shorting operation.
Bilateral Shorted Operators and Parallel Sums
For t = 0, the tensor operator At is just the number operator, for t = 1, it is the operator of total spin, etc.
The Two-Body Random Ensemble in Nuclei
It is obvious that the commutator [T (s), T (t)] differs from zero and does not lie in the linear space spanned by the operators T . A recoupling of the operators shows, in fact, that the commutator is a sum of three–body operators.
The Two-Body Random Ensemble in Nuclei
Two types of Wick contractions occur: (a) Those where contractions connect pairs of operators separately within the group of the first four and of the second four operators, and (b) those where at least two operators of the first group of four are contracted with the same number of operators of the second group.
The Two-Body Random Ensemble in Nuclei
To facilitate this, we first reformulate classical mechanics, representing classical observables on phase space by hermitian operators on Hilbert space , and in particular representing the Liouville density by a quasidensity operator [7, 8, 5] (the Groenewold operator).
