Dual Sets Of Envelopes And Characteristic Regions Of Quasipolynomials Sui Sun Cheng by Sui Sun Cheng, Yi-zhong Lin 9789814277273, 9814277274 instant download after payment.

In this book, we present a formal theory of the Cheng-Lin envelope method, which is completely new, yet simple and precise. This method is both simple since only basic Calculus concepts are needed for understanding -- and precise, since necessary and sufficient conditions can be obtained for functions such as polynomials containing more than four parameters.

Since the underlying principles are relatively simple, this book is useful to college students who want to see immediate applications of what they learn in Calculus; to graduate students who want to do research in functional equations; and to researchers who want references on roots of quasi-polynomials encountered in the theory of difference and differential equations.
