This book is based on a course for first-semester science students, held by the second author at the University of Zurich several times. Its goal is threefold: to have students learn a minimal working knowledge of linear algebra, acquire some computational skills, and familiarize them with mathematical language to make mathematical literature more accessible. Therefore, we give precise definitions, introduce helpful notations, and state any results carefully worded. We provide no proofs of these results but typically illustrate them with numerous examples. Additionally, for better understanding, we often give supporting arguments for why they are valid.

A concise introduction to linear algebra for first-semester science students Each section contains a problem set with solutions in the appendix Focuses on precise definitions, uses helpful notations and illustrates results with numerous examples

Autorentext

****Manuel Benz is a high school teacher working in Zurich. After his studies in theoretical particle physics and mathematics, he taught, together with Thomas Kappeler, several courses at the University of Zurich. The courses' goal: To find a bridge between high school and university mathematics and to motivate young students to pursue their studies in mathematics.
Thomas Kappeler was an Emeritus Professor at the University of Zurich. He started his academic career with a thesis on bilinear integrals, was a visiting professor at four universities in the United States and following a professorship at the Ohio State University, he was appointed professor at the University of Zurich. His research focused, among others, on global analysis and dynamical systems. In his lectures, he took great care to present the topics with precision and clarity.
