In this expository and survey paper, along one of main lines of bounding theratio of two gamma functions, we look back and analyse some inequalities, thecomplete monotonicity of several functions involving ratios of two gamma or$q$-gamma functions, the logarithmically complete monotonicity of a functioninvolving the ratio of two gamma functions, some new bounds for the ratio oftwo gamma functions and divided differences of polygamma functions, and relatedmonotonicity results.

Bounds for the ratio of two gamma functions--From Gautschi's and Kershaw's inequalities to completely monotonic functions
