A Characterization of the Exponential Function

Journal of the London Mathematical Society, 1986
Let E be the class of all entire functions \(f(t)=\sum^{\infty}_{k=0}a_ kt^ k\) with \(a_ 0=1\), \(a_ k>0\) for \(k=1,2,3,...\), and \(\int^{\infty}_{0}t^ k(f(t))^{-1}dt=1/a_ k, k=0,1,2,... \). A conjecture of Renyi and Vincze is verified by proving the exponential function \(f(t)=e^ t\) is the only member of E.

EXPONENTIAL AND LOGARITHMIC FUNCTIONS

1981
Publisher Summary This chapter discusses exponential and logarithmic functions. Exponential functions arise in nature and are useful in chemistry, biology, and economics, as well as in mathematics and engineering. Logarithms can be viewed as another way of writing exponents.
