34 Ergodic Chains

EBook Description: Until this point in the book, results have been derived or proven, or at least the nature of the proof has been indicated. However, proofs of the techniques of Sections 34, 35 and 36 as well as the core concept of Chapter 37 are beyond this book and have been omitted. Do not let this deter you.

its book of mathematics on numerical analysis.

35 Mixed Chains

In this chapter we learn how to analyze Markov chains that consists of transient and absorbing states. Later we will see that this analysis extends easily to chains with (nonabsorbing) ergodic states.

36 Poisson Processes

We are going to look at a random process that typifies what most of us think of as random. This process has the added virtues that it is easy to work with and it is used a great deal in mathematical modeling. In fact, it may be used more than any other process of its type. In particular what I am talking about is the Poisson1 process which is described by both the Poisson distribution and the exponential distribution.

37 A Little Game Theory

Game theory is one of the most interesting topics of discrete mathematics. The principal theorem of game theory is sublime and wonderful. We will merely assume this theorem and use it to achieve some of our early insights. To appreciate the theorem it is not necessary to know the proof. Do not let any math pedant tell you otherwise.1 By a game mathematics refers to a conflict between individuals (or entities) with conflicting goals.

Introduction to Methods of Applied Mathematics

For the past few years I have been working on an open source textbook. It contains material on calculus, functions of a complex variable, ordinary differential equations, partial differential equations and the calculus of variations. The text is still under development, but I believe that the current version will be useful for students and instructors.

Matrix Analysis and Applied Linear Algebra

The purpose of this text is to present the contemporary theory and applications of linear algebra to university students studying mathematics, engineering, or applied science at the postcalculus level. Because linear algebra is usually encountered between basic problem solving courses such as calculus or differential equations and more advanced courses that require students to cope with mathematical rigors, the challenge in teaching applied linear algebra is to expose some of the scaffolding while conditioning students to appreciate the utility and beauty of the subject. Effectively meeting this challenge and bridging the inherent gaps between basic and more advanced mathematics are primary goals of this book.

Discrete Mathematics with Algorithms

This first-year course in discrete mathematics requires no calculus or computer programming experience. The approach stresses finding efficient algorithms, rather than existential results. Provides an introduction to constructing proofs (especially by induction), and an introduction to algorithmic problem-solving. All algorithms are presented in English, in a format compatible with the Pascal programming language. Contains many exercises, with answers at the back of the book (detailed solutions being supplied for difficult problems).

Linear Algebra for Informatics

These are the lecture notes and tutorial problems for the Linear Algebra module in Mathematics for Informatics 3 (MAT-2-mi3/am3i). They are a revised version of the ones used in the 2004-2005 session, which were themselves revised due to changes in the syllabus from the ones used in the 2003-2004 session.

One Variable Advanced Calculus

The difference between advanced calculus and calculus is that all the theorems are proved completely and the role of plane geometry is minimized. Instead, the notion of completeness is of preeminent importance. Silly gimmicks are of no significance at all. Routine skills involving elementary functions and integration techniques are supposed to be mastered and have no place in advanced calculus which deals with the fundamental issues related to existence and meaning. This is a subject which places calculus as part of mathematics and involves proofs and definitions, not algorithms and busy work.

Algorithmic Mathematics

This text contains sufficient material for a one-semester course in mathematical algorithms, for second year mathematics students. The course requires some exposure to the basic concepts of discrete mathematics, but no computing experience. The aim of this course is twofold. Firstly, to introduce the basic algorithms for computing exactly with integers, polynomials and vector spaces. In doing so, the student is expected to learn how to think algorithmically and how to design and analyze algorithms.
