On the logarithm of the derivative operator

Classical Analysis and ODEs 2012-09-12 v2 Mathematical Physics math.MP

Abstract

We study the properties of the logarithm of the derivative operator and show that its action on a constant is not zero, but yields the sum of the logarithmic function and the Euler-Mascheroni constant. We discuss more general aspects concerning the logarithm of an operator for the study of the properties of the Bessel functions.
