The Weyl algebra is the algebra generated by two letters \u003ci\u003eU\u003c\/i\u003e and \u003ci\u003eV\u003c\/i\u003e subject to the commutation relation \u003ci\u003eUV − VU = I\u003c\/i\u003e. It is a classical result that normal ordering powers of \u003ci\u003eVU\u003c\/i\u003e involve the Stirling numbers. \u003c\/p\u003e\u003cp\u003eThe book is a one-stop reference on the research activities and known results of normal ordering and Stirling numbers. It discusses the Stirling numbers, closely related generalizations, and their role as normal ordering coefficients in the Weyl algebra. The book also considers several relatives of this algebra, all of which are special cases of the algebra in which \u003ci\u003eUV − qVU = hVs\u003c\/i\u003e holds true. The authors describe combinatorial aspects of these algebras and the normal ordering process in them. In particular, they define associated generalized Stirling numbers as normal ordering coefficients in analogy to the classical Stirling numbers. In addition to the combinatorial aspects, the book presents the relation to operational calculus, describes the physical motivation for ordering words in the Weyl algebra arising from quantum theory, and covers some physical applications. \u003c\/p\u003e","brand":"Taylor \u0026 Francis","offers":[{"title":"Default Title","offer_id":45600558055662,"sku":"9781466579880","price":260.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/9612\/7726\/files\/9781466579880.jpg?v=1721473526","url":"https:\/\/bookland.com.au\/products\/commutation-relations-normal-ordering-and-stirling-numbers-hardback","provider":"Book Land AU","version":"1.0","type":"link"}
