Elementary Abstract Algebra
W Edwin Clark · University of South Florida
This book is intended for a one semester introduction to abstract algebra. We assume that students have some familiarity with basic set theory linear algebra and calculus. But very little of this nature will be needed To a great extent the course is self contained except for the requirement of a certain amount of mathematical maturity. And hopefully the student's level of mathematical maturity will increase as the course progresses.

Numerically Solving Ordinary Differential Equations
Stuart Brorson · Northeastern University
The booklet covers basic Euler solvers, Runge-Kutta, and linear multistep methods and discusses explicit vs. implicit methods. It discusses stability and the stability domains of some of the methods and talks about adaptive methods and the concept of stiffness and concluding with a chapter on symplectic methods and why they are important. Beyond the solver algorithms, the book includes many example ODEs and shows their solutions using the methods discussed. Matlab programs accompany the text.

Complex Variables with Applications
Jeremy Orloff · Massachusetts Institute of Technology
Complex analysis is a basic tool in many mathematical theories. By itself and through some of these theories it also has a great many practical applications. There are a small number of far-reaching theorems that we’ll explore in the first part of the class. Along the way, we’ll touch on some mathematical and engineering applications of these theorems. The last third of the class will be devoted to a deeper look at applications.

The Grim Educator
Cathryn van Kessel · University of Alberta
This site is for educators (and anyone else) who may be interested in the ways that death and evil shape how we interact with others and shape our world.By engaging with the ideas of Hannah Arendt and Ernest Becker, as well as borrowing from terror management theory (TMT) in social psychology, we hope to provoke thinking about how our conscious and unconscious approaches to evil and death impact education (and our lives).We hope to update this site regularly with new ideas and lessons, so keep c

Combinatorics
Joy Morris · University of Lethbridge
Combinatorics is an upper-level introductory course in enumeration, graph theory, and design theory. The text focuses on combinations and arrangements of discrete structures. There are five major branches of combinatorics that we will touch on in this course: enumeration, graph theory, Ramsey Theory, design theory, and coding theory. We will focus on enumeration, graph theory, and design theory, but will briefly introduce the other two topics.

Six Steps To Job Search Success
LibreTexts · LibreTexts
This book is a practical discussion of six actionable steps that students can take to land a job regardless of the market. Whether the estimate is 25% unemployment or single-digit unemployment, that number doesn't apply to any one student. For any individual, the unemployment rate is 0% or 100%. One either has a job or doesn't. When any one person is looking for a job and there is 10% unemployment, that person just wants to be one of the nine people that has a job.
