A completely monotonic function involving the tri-gamma function and with degree one

Abstract In the paper the authors introduce the concept of completely monotonic degrees of nonnegative functions on ( 0 , ∞ ) and proves that a function involving the difference between the tri-gamma function ψ ′ ( x ) and a proper fraction of x is completely monotonic of degree 1 on ( 0 , ∞ ) .
