... The proof of the Theorem The q-difference operator and the q-shift operator η are defined by D q {f(a)} = 1 a (f(a) − f(aq)) and η{f (a)} = f (aq), respectively. In [2] Chen and Liu construct the ... construct the operator θ = η −1 D q . Based on these, they introduce a q-exponential operator: E(bθ)= ∞  n=0 (bθ) n q ( n 2 ) (q; q) n . For E(bθ), there hold the following opera...

Since the dimension of the row-span of a matrix is equal to the dimension of its column-span, we can equally well study the dimension of the space spanned by the columns of the ... the reflection representation of a finite Coxeter group. This is essentially what we are looking at. (The defining representation of S n consists of the d...
