A property of logarithmically absolutely monotonic functions and the logarithmically complete monotonicity of a power-exponential function

In the article, a notion "logarithmically absolutely monotonic function" is introduced, an inclusion that a logarithmically absolutely monotonic function is also absolutely monotonic is revealed, the logarithmically complete monotonicity and the logarithmically absolute monotonicity of the function $\bigl(1+\fracαx\bigr) ^{x+β}$ are proved, where $α$ and $β$ are given real parameters, a new proof for the inclusion that a logarithmically completely monotonic function is also completely monotonic is given, and an open problem is posed.
