The notation convention chosen here (with W 0 and W −1) follows the canonical reference on the Lambert W function by Corless, Gonnet, Hare, Jeffrey and Knuth. [3]The name "product logarithm" can be understood as follows: since the inverse function of f(w) = e w is termed the logarithm, it makes sense to call the inverse "function" of the product we w the "product logarithm".
The Lambert W function is the function () ... We may use the theorem to compute the Taylor series of () at = We take () = and = Recognizing that =, ...
This is a list of special function eponyms in ... Paul Émile Appell (1855–1930): Appell hypergeometric series, ... Johann Heinrich Lambert: Lambert W function;
In fact, the set of functions with a convergent Taylor series is a meager set in the Fréchet space of smooth functions. Even if the Taylor series of a function f does converge, its limit need not be equal to the value of the function f (x). For example, the function
In particular, its Taylor formal series diverges: ... where is the Lambert W function. This approximation is derived via an asymptotic method, but it stays ...
There are various types of generating functions, including ordinary generating functions, exponential generating functions, Lambert series, Bell series, and Dirichlet series. Every sequence in principle has a generating function of each type (except that Lambert and Dirichlet series require indices to start at 1 rather than 0), but the ease ...
The Wright omega function along part of the real axis. ... denoted ω, is defined in terms of the Lambert W function as: ... Its Taylor series around the point = ...
It is the value of W(1), where W is Lambert's W function. The name is derived from the alternate name for Lambert's W function, the omega function. The numerical value of Ω is given by Ω = 0.56714 32904 09783 87299 99686 62210... (sequence A030178 in the OEIS). 1/Ω = 1.76322 28343 51896 71022 52017 76951... (sequence A030797 in the OEIS).
