The Lagrange Multiplier Method for Dirichlet's Problem [PDF]
Mathematics of Computation, 1981 The Lagrange multiplier method of Babuška for the approximate solution of Dirichlet’s problem for second order elliptic equations is reformulated. Based on this formulation, new estimates for the error in the solution and the boundary flux are given. Efficient methods for the solution of the approximate problem are discussed.

A Note on the Method of Lagrange Multipliers with Random Variables
SSRN Electronic Journal, 2016 I examine a simple optimisation problem to illustrate how to correctly apply the method of Lagrange multipliers to extremisation problems involving random variables. Such problems are commonplace in economics, but rigorous methods are often not taught. This is a shortcoming in economics pedagogy that it is both easy and worthwhile to remedy.
