• Logarithmically completely monotonic functions
• Completely monotonic functions
• Gamma functions
• Psi (or digamma) functions
• Polygamma functions

The main object of this work is to give some conditions for a class of functions to be logarithmically completely monotonic. Our result is shown to be an extension of a result which was proven in the recent literature on this subject.
