33 The Gambler's Ruin
There are many variations of the gambler's ruin problem, but a principal one goes like
this. We have i dollars out of a total of n. We flip a coin which has probability p of landing
heads, and probability q = 1 ! p of landing tails. If the coin lands heads we gain another dollar,
otherwise we lose a dollar.
34 Ergodic Chains
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.
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.
