The \(\alpha\)-analogues of r-Whitney Numbers via Normal Ordering
Hye Kyung Kim · Journal of Advances in Mathematics and Computer Science · 2022
The normal ordering of an integral power of the number operator a\(^\dagger\)a in terms of boson annihilation a and creation a\(^\dagger\) operators is expressed with the help of the Stirling numbers of the second kind. The normal ordering problems directly links the problems to...
