Let @F"m(x)=-x^m@j^(^m^)(x), where @j denotes the logarithmic derivative of Euler's gamma function. Clark and Ismail prove in a recently published article that if m@?{1,2,...,16}, then @F"m^(^m^) is completely monotonic on (0,~), and they conjecture that this is true for all natural numbers m. We disprove this conjecture by showing that there exists an integer m"0 such that for all m=m"0 the function @F"m^(^m^) is not completely monotonic on (0,~).
