Semiparametric and Nonparametric Methods in Econometrics

Standard methods for estimating empirical models in economics and many other fields rely on strong assumptions about functional forms and the distributions of unobserved random variables. Often, it is assumed that functions of interest are linear or that unobserved random variables are normally distributed.

The Logarithmic Potential: Discontinuous Dirichlet and Neumann Problems

This book studies fundamental properties of the logarithmic potential and their connections to the theory of Fourier series, to potential theory, and to function theory. The material centers around a study of Poisson's integral in two dimensions and of the corresponding Stieltjes integral. The results are then extended to the integrals in terms of Green's functions for general regions.

FAST FLUENCY - Communication in English for the International Age

There are twenty lessons, and teachers may cover them in any order. They are not graded, and each one contains very simple as well as more difficult and less frequently-used language items. While there is a certain logic to the presentation of the subject matter of the conversations, the level of difficulty remains more or less uniform throughout.

Analytic Number Theory: An Introductory Course

This valuable book focuses on a collection of powerful methods of analysis that yield deep number-theoretical estimates. Particular attention is given to counting functions of prime numbers and multiplicative arithmetic functions. Both real variable ("elementary") and complex variable ("analytic") methods are employed. The reader is assumed to have knowledge of elementary number theory (abstract algebra will also do) and real and complex analysis. Specialized analytic techniques, including transform and Tauberian methods, are developed as needed.

The Language of Functions and Graphs An Examination Module for Secondary Schools
