### What is matrix theory and why is it important?

A matrix is a rectangular array of numbers or symbols that can be used to represent various mathematical objects and operations. Matrix theory is the study of matrices and their properties, such as determinants, inverses, eigenvalues, eigenvectors, rank, trace, etc. Matrix theory also explores how matrices can be used to solve various problems in linear algebra, such as systems of linear equations, linear transformations, vector spaces, bases, orthogonality, etc.

Matrix theory is important because it has many applications in various fields of science and engineering, such as physics, chemistry, biology, computer science, electrical engineering, mechanical engineering, etc. For example, matrices can be used to model physical phenomena such as rotations, vibrations, waves, quantum mechanics, relativity, etc. Matrices can also be used to perform computations such as matrix multiplication, inversion, decomposition, etc., which are essential for numerical analysis, optimization, machine learning, data mining, image processing, etc.

### Who was Gantmacher and what did he contribute to matrix theory?

Felix Ruvimovich Gantmacher (1908-1990) was a Soviet mathematician who specialized in matrix theory and its applications. He was a professor at Moscow State University and Moscow Institute of Physics and Technology. He was also a corresponding member of the Soviet Academy of Sciences and a recipient of several awards and honors.

Gantmacher made significant contributions to various aspects of matrix theory, such as matrix calculus, canonical forms, stability theory, perturbation theory, matrix inequalities, functions of matrices, etc. He also wrote several books and papers on these topics, including his two-volume masterpiece Theory of Matrices, which is considered one of the most comprehensive and authoritative texts on the subject.

### What are the main topics covered in his book Theory of Matrices?

Theory of Matrices by Gantmacher consists of two volumes, each containing seven or eight chapters. The first volume covers the following topics:

Basic concepts and definitions of matrices and linear operators

Theoretical and practical methods of solving systems of linear equations

Characteristic and minimal polynomials of matrices and their applications

Functions of matrices and their properties

### What is DJVU format and how to read it?

DJVU is a file format that is designed to store scanned documents, especially those containing a combination of text, line drawings, and photographs. DJVU files are typically smaller than PDF files, but retain a high quality of image compression. DJVU files can be viewed using various software applications, such as WinDjView, DjVuLibre, or Sumatra PDF. You can also use online tools such as DjVu Viewer or DjVu to PDF Converter to open or convert DJVU files.

## How to use Gantmacher's book effectively

### What are the prerequisites and level of difficulty of the book?

### What are the prerequisites and level of difficulty of the book?

Gantmacher's book is meant for advanced undergraduate or graduate students in mathematics or related fields who have some background in linear algebra and abstract algebra. The book assumes that the reader is familiar with basic concepts and results of matrices and linear operators, such as determinants, inverses, eigenvalues, eigenvectors, rank, trace, etc. The book also uses some notions and techniques from set theory, logic, analysis, and algebra, such as sets, functions, relations, equivalence classes, groups, rings, fields, polynomials, limits, continuity, differentiation, integration, etc. The book does not require any knowledge of calculus, but some familiarity with differential equations and complex analysis may be helpful for some topics.

The book is not an easy read, as it covers a lot of material in depth and rigor. The book also contains many exercises that range from simple computations to challenging proofs. The book requires a high level of mathematical maturity and abstraction from the reader. However, the book also provides many examples, explanations, and motivations for the concepts and results. The book is a valuable resource for anyone who wants to learn matrix theory thoroughly and systematically.

### How to navigate through the book and find relevant information?

The book is organized into two volumes, each containing seven or eight chapters. Each chapter is divided into several sections, each containing a main theorem or result, followed by its proof or derivation, and then by some corollaries or applications. Each section also contains some remarks or comments that provide additional insights or historical notes on the topic. At the end of each section, there are several exercises that test the reader's understanding and skills on the topic.

To navigate through the book and find relevant information, the reader can use the table of contents, the index, and the references provided at the beginning and end of each volume. The table of contents gives an overview of the main topics covered in each chapter and section. The index lists the keywords and terms used in the book, along with their page numbers. The references provide a list of books and papers that are cited or consulted by the author, along with their bibliographic information.

The reader can also use the cross-references within the text to locate related topics or results. The author uses various symbols and abbreviations to indicate cross-references, such as (I.2.3) for Theorem 3 in Section 2 of Chapter I, or [5] for Reference 5 at the end of Volume I. The reader can also use footnotes to find additional information or explanations on certain points.
