q-Poisson, q-Dobinski, q-Rota and q-coherent states

The q-Dobinski formula may be interpreted as the average of powers of random variable X q with the q-Poisson distribution. Forty years ago Rota G. C. [1] proved the exponential generating function for Bell numbers B n to be of the form ∞ n=0 x n n! (B n) = exp(e x − 1) (1) using the linear functional L such that L(X n) = 1, n ≥ 0 (2) Then Bell numbers (see: formula (4) in [1]) are defined by L(...

Q-dependence of Deep Inelastic Sum Rules*

In this talk, I will concentrate on Q2-dependence of deep inelastic sum rules. I will first give a modern definition of deep-inelastic sum rules and then discuss physical origins of their scaling violation at finiteQ2. Following this, I discuss a few well-known examples, in particular, the Bjorken sum rule, which is at the center of interest of this symposium. Finally, I consider the Q2 → 0 lim...

Scalar form factors f ππ ( Q 2 ) and f KK ( Q 2 ) with light - cone QCD sum rules

In this article, we calculate the scalar form factors fππ(Q 2) and fKK(Q 2) within the framework of the light-cone QCD sum rules approach. The numerical value of fππ(Q 2) changes quickly with the variation of Q2 at about Q2 < 0.1GeV 2, while fKK(Q 2) has rather good behavior at small momentum transfer, the value fKK(0) = 2.21 +0.35 −0.19GeV is compatible with the values from the leading order c...

CYCLIC q-MZSV SUM

We present a family of identities ‘cyclic sum formula’ and ‘sum formula’ for a version of multiple q-zeta star values. We also discuss a problem of q-generalization of shuffle products. Introduction and notation The classical idea of introducing an additional parameter to an expression or formula we wish to deal with, is quite fruitful in many situations. This may simplify a proof of the corres...
