Combinatorial solutions to normal ordering of bosons.
Czechoslovak Journal of Physics, 55(11) pp. 1335–1341.
We present a combinatorial method of constructing solutions to the normal ordering of boson operators. Generalizations of standard combinatorial notions — the Stirling and Bell numbers, Bell polynomials and Dobinski relations — lead to calculational tools, which allow to find explicitly normally ordered forms for a large class of operator functions.
