## Introduction

### What is a stochastic process?

A stochastic process is a mathematical model that describes the evolution of a random phenomenon over time or space. For example, the number of customers arriving at a bank, the price of a stock, the temperature of a room, or the position of a particle are all examples of stochastic processes. A stochastic process can be characterized by its state space (the set of possible values that the random phenomenon can take) and its index set (the set of possible times or locations that the random phenomenon can be observed).

### Why study stochastic processes?

Stochastic processes are widely used in various fields of science, engineering, economics, and social sciences to model complex systems that involve uncertainty, randomness, or variability. By studying stochastic processes, we can gain insight into the behavior and properties of these systems, such as their long-term trends, stability, equilibrium, optimal control, risk analysis, etc. Stochastic processes also provide us with powerful tools and techniques to analyze data and make predictions or decisions based on incomplete or noisy information.

### Who is Sheldon M Ross?

He has also received numerous awards and honors for his research and teaching excellence, such as the INFORMS Expository Writing Award, the INFORMS Simulation Society Lifetime Professional Achievement Award, and the George E. Kimball Medal.

## Overview of the book

### Main topics covered

The book Stochastic Processes by Sheldon M Ross covers a wide range of topics in stochastic processes theory and applications. The book consists of 11 chapters:

• Chapter 1: Introduction. This chapter introduces some basic concepts and definitions related to stochastic processes, such as probability spaces, random variables, expectation, conditional probability and expectation, independence, etc.

• Chapter 2: The Poisson Process. This chapter introduces one of the most important and widely used stochastic processes, the Poisson process, which models the occurrence of events in a continuous time interval. The chapter discusses the properties, distributions, and applications of the Poisson process, as well as some extensions and generalizations, such as the compound Poisson process, the nonhomogeneous Poisson process, and the conditional Poisson process.

• Chapter 3: Markov Chains. This chapter introduces another fundamental stochastic process, the Markov chain, which models the evolution of a discrete state system in discrete time. The chapter discusses the properties, classifications, and applications of Markov chains, as well as some important results, such as the Chapman-Kolmogorov equations, the Markov property, the transition matrix, the stationary distribution, the ergodic theorem, etc.

• Chapter 4: The Exponential Distribution and the Poisson Process. This chapter revisits the Poisson process and shows how it can be derived from the exponential distribution, which models the time between successive events in a Poisson process. The chapter also discusses some applications and variations of the exponential distribution and the Poisson process, such as the memoryless property, the lack of aging property, the gamma distribution, the Erlang distribution, etc.

• Chapter 5: Continuous-Time Markov Chains. This chapter extends the concept of Markov chains to continuous time, where the state transitions occur according to a Poisson process. The chapter discusses the properties, classifications, and applications of continuous-time Markov chains, as well as some important results, such as the Kolmogorov forward and backward equations, the embedded Markov chain, the birth-death process, etc.

• Chapter 6: Renewal Theory. This chapter introduces another important class of stochastic processes, the renewal processes, which model the occurrence of events that are governed by independent and identically distributed interarrival times. The chapter discusses the properties and applications of renewal processes, as well as some important results, such as the renewal equation, the renewal reward theorem, the elementary renewal theorem, etc.

• Chapter 7: Brownian Motion and Stationary Processes. This chapter introduces two more classes of stochastic processes that are widely used in various fields. Brownian motion is a stochastic process that models the random motion of a particle in a fluid or gas. Stationary processes are stochastic processes that have invariant statistical properties over time or space. The chapter discusses the properties and applications of Brownian motion and stationary processes, as well as some important results, such as the Wiener process, the Gaussian process, the autocorrelation function, etc.

• Chapter 8: Queueing Theory. This chapter applies stochastic processes to model and analyze queueing systems, which are systems that involve customers arriving at a service facility and waiting in line for service. The chapter discusses various types of queueing systems and their performance measures, such as queue length, waiting time, utilization rate, etc. The chapter also introduces some standard queueing models and their solutions, such as the M/M/1 queue, the M/M/c queue, etc.

• Chapter 9: Martingales. This chapter introduces another powerful tool for studying stochastic processes, namely martingales. Martingales are stochastic processes that have a fair game property, meaning that their future values do not depend on their past values or information. The chapter discusses the properties and applications of martingales, as well as some important results, such as Doob's optional stopping theorem, the martingale convergence theorem, etc.

• Chapter 10: Optimal Stopping. This chapter applies martingales to solve optimal stopping problems, which are problems that involve deciding when to stop a stochastic process to maximize or minimize some objective function. The chapter discusses various types of optimal stopping problems and their solutions, such as the secretary problem, the gambler's ruin problem, etc.

• Chapter 11: Markov Decision Processes. This chapter applies stochastic processes to model and solve Markov decision processes, which are problems that involve making optimal decisions in a dynamic system that evolves according to a Markov chain. The chapter discusses various types of Markov decision processes and their solutions, such as finite-horizon problems, infinite-horizon problems, discounted problems, average-reward problems, etc.
