This function is continuous, as per the work of Paulsen [2016]. This solution introduces into statistics the law of the one-and-a-half logarithm. Sometimes the natural growth processes do not yield to the law of the logarithm, and a double logarithm weakens the growth too much. The law of the one-and-a-half logarithm proposed in this study might be the solution}, title={Remarks about the square equation : functional square root of a logarithm}, type={artykuł}, keywords={functional square root, fractional iteration, power series, logarithm, semigroup}, }
