29). 24). 3). 30) due to Hsu and Shiue, which uniﬁed many of the previous generalizations of the Stirling numbers. After surveying many of their properties, a q-deformation and a (p, q)-deformation are treated. At the end of the chapter we brieﬂy mention a selection of further recent generalizations of the Stirling numbers. In Chapter 5 we focus on the Weyl algebra, which is the complex algebra generated by U and V satisfying U V − V U = h for some h ∈ C. After presenting some elementary properties and a few remarks on its history, we give an introduction to elementary aspects of quantum mechanics (stressing its connection to the Weyl algebra).

The more complex word D2 XD can be written as DDXD = DXDD + DD = DXD2 + D2 . 6), one can transform each word in X and D into a sum of words, where each of these words has all the powers of D to the right. 23 A word ω in the letters X and D is in normal ordered form if ω = ar,s X r Ds for r, s ∈ N0 (and arbitrary coeﬃcients ar,s ∈ C). An expression consisting of a sum of words is called normal ordered if each of the summands is normal ordered. The process of bringing a word (or a sum of words) into its normal ordered form is called normal ordering.

There are several methods for solving recurrence relations: (1) guess and check, (2) iteration (repeated substitution), (3) characteristic polynomial, and (4) generating functions. 1 Guess and Check The ﬁrst method is based on guessing a solution and then proving by induction (or any other method) that it is correct. Usually, ﬁnding the right guess is a problem of art! For example, let an be the sequence which satisﬁes the recurrence relation an = k · an−1 , for all n ≥ 1, with the initial condition a0 = 1.
