Three classes of logarithmically completely monotonic functions involving gamma and psi functions
Abstract By a simple approach, two classes of functions involving Euler’s gamma function and originating from certain problems of traffic flow are proved to be logarithmically completely monotonic and a class of functions involving the psi function is showed to be completely monotonic.
