  • Abstract
    The Lambert W function fulfills W(y)· eW(y) = y. With the choice y = log (x) it can hence be applied to invert the function f (x) = x · log(x), which is of some interest in the problems discussed. Further applications of the Lambert W function in information theory are briefly surveyed.
