Abstract :We presented some monotonicity properties for the k-generalized digamma function $\\psi_{k}(h)$ and we established some new bounds for $\\psi_{k}^{(s)}(h),$ $s\\in \\mathbb{N}\\cup\\{0\\},$ which refine recent resultsKeywords : Gamma function, digamma function, polygamma function, completely monotonic function, asymptotic expansion, inequalities
