On the LambertW function
نویسندگان
چکیده
The Lambert W function is defined to be the multivalued inverse of the function w 7→ we. It has many applications in pure and applied mathematics, some of which are briefly described here. We present a new discussion of the complex branches of W , an asymptotic expansion valid for all branches, an efficient numerical procedure for evaluating the function to arbitrary precision, and a method for the symbolic integration of expressions containing W .

Solving Share Equations in Logit Models Using the LambertW Function
Though individual demand and supply equations can readily be expressed in logit models, closed-form solutions for equilibrium shares and prices are intractable due to the presence of products of polynomial and exponential terms. This hinders the employment of logit models in theoretical studies, and also makes it difficult to develop reduced-form expressions for share and price as a function of...
متن کاملComputing the Lambert W function in arbitrary-precision complex interval arithmetic
We describe an algorithm to evaluate all the complex branches of the LambertW function with rigorous error bounds in interval arithmetic, which has been implemented in the Arb library. The classic 1996 paper on the Lambert W function by Corless et al. provides a thorough but partly heuristic numerical analysis which needs to be complemented with some explicit inequalities and practical observat...
متن کاملNon-uniform Sampling Delta Modulation -Principles of Parameters Design
The parameters design of 1-bit adaptive delta modulations (ADM) systems with uniform sampling rate is well known. Analytical study of delta modulations with sampling rate adaptation have been carried out few years ago. The described ADM systems encode the input signal by changing the sampling intervals and/or step size according to its time-varying slope characteristics. A proposition for desig...
متن کاملOrthogonal Range Search using a Distributed Computing Model
We present a novel approach for distributed orthogonal range search on a set ofN points stored on n nodes. The non-redundant rainbow skip graph [Goodrich et al [12] is used to coordinate message passing among nodes. We show that the maximum number of levels L in such a graph is L = W (n ln 2)/ ln 2, where W is the lambertW function. Experimental validation is performed using 24 nodes, with N = ...
متن کاملA copper electrolysis cell model including effects of the ohmic potential loss in the cell
A computational model of a Cu electrolysis cell is presented. The model includes the microscopic mass transfer and electric field effects, as well as the effects of the ohmic loss of potential in the cell bulk electrolyte. A lumped (0D) estimate for the cell ohmic loss is created by utilizing a 3D electric fieldmodel of the cell and the LambertW-function is applied to include the effects of ohm...
