Combinatorial identities on \(q\)-harmonic numbers

2011
Summary: By means of the \(q\)-finite differences and the derivative operator, we derive, from an alternating \(q\)-binomial sum identity with a free variable \(x\), several interesting identities concerning the generalized \(q\)-harmonic numbers.
