Operators’ ordering: from Weyl ordering to normal ordering
Science China: Physics, Mechanics and Astronomy, 2011By virtue of the technique of integration within an ordered product of operators we present a new approach to obtain operators’ normal ordering. We first put operators into their Weyl ordering through the Weyl-Wigner quantization scheme, and then we convert the Weyl ordered operators into normal ordering by virtue of the normally ordered form of the ...

The operator canonical perturbation theory (CPT) is an efficient tool for solving the molecular vibration-rotation Schrödinger equation. The corresponding Watson Hamiltonian can be written using angular momentum cylindrical ladder operators (Jz, J± = Jx ∓

Normal ordering in the shift algebra and the dual of Spivey’s identity
Quaestiones Mathematicae. Journal of the South African Mathematical Society, 2022Spivey’s Bell number identity involving Stirling numbers of the second kind was derived by Spivey considering set partitions. Since its original derivation it has been derived (and generalized) by many authors using different techniques.

The ⊲-ordering on normal ultrafilters
Journal of Symbolic Logic, 1985Ifκis a measurable cardinal, then it is a well-known fact that there is at least one normal ultrafilter overκ. In [K-1], Kunen showed that one cannot say more without further assumptions, for ifUis a normal ultrafilter overκ, thenL[U] is an inner model of ZFC in whichκhas exactly one normal measure.
