The authors are pleased to see the text of Linear Algebra in English version for Chinese students at the university level. This book not only shows and explains the useful and beautiful knowledge of mathematics, but also presents the structure and arrangement of linear algebra.
1. The Significance of this Book “One sows a seed in the spring, thousands of grains autumn to him brings.” All the Chinese students had strict training step by step in the study of mathematics before they become a university student. Intuitive and experimental methods are basic and important study patterns, but the target of mathematical education is to form and improve the deductive ability. So far, Chinese students have distinct and excellent achievement in international comparison of mathematics all over the world. As the improvement in educational exchange internationally, more and more Chinese students choose to study abroad at their university level or higher level. Therefore, mathematical textbook on the basis of Chinese students’ mathematical study in English version is urgent needed and essential. This book provides the strong support for the students who will study Economics, Finance, Management, Social Science and so on in local country or abroad. 2. The Difference between Linear Algebra and Calculus Calculus is mostly about symmetric and beautiful things.One is differentiation, another is its inverse—integration. Calculus can help us to solve the problems in continuous and analog situation in our life. How about other discrete and digital things? Linear algebra can give us help, and vector and matrix are the second type of language we need to study and understand. Study to read a matrix is the most meaningful and key goal in linear algebra, and it gives wide variety for this mathematical area. There are three examples given here:Triangular Matrix，Symmetric Matrix，Orthogonal Matrix. 3. The Structure of this Book This book organizes the content basis on the logical relationship among number, matrix and vector. It lists the structure from determinant, to matrix, to solve system of linear equations, to vector, to structure of solutions, to eigenvalue and eigenvector, to quadratic form finally. Here is the structure of this book: Chapter 1 starts with determinant. There are three important points about the determinant. The first is the definition, the second is property, and the last is its expansion. The Cramer’s rule is given basis on these three points. Chapter 2 gives all the varieties of matrix. After the study of concept of matrix, it begins with algebra operations, and shows some special matrices. It is following with how to partition matrix, and how to find the inverse of matrix. After given the elementary operations and elementary matrix, this chapter is ended by rank of matrix. Chapter 3 shows the relationship between matrix and the system of linear equations. Certainly, it is the most important that using matrix to solve the system of linear equations. Gaussian Elimination Method is the most helpful technique. Chapter 4 begins studying vector. Definition and operation are two basic study points. Linear dependence and rank of vector are two new knowledge structures. Chapter 5 is mainly basis on chapter 3 and chapter 4. Here is similar framework for giving the structure of solutions of homogeneous and nonhomogeneous system of linear equations. Both these two parts discuss the corresponding property firstly, and give the details of their structure respectively. Chapter 6 is mostly in eigenvalue and eigenvector. Besides the definition of them, there are three points of matrix using both two of them which are diagonalization, similar matrix and real symmetric matrix. Chapter 7 is quadratic form which has three points. The first point is about the definition. The first is the basic, almost, which is the principal and organization order of studying mathematical knowledge. The second is the classification of quadratic form and positive definite matrix. The last is criterion of congruent matrix. 4. Help with this Book “Not knowing that flower close to the water earlier blow, I wonder if it’s last winter’s unmelted snow.” This textbook is emerged with the strong support from Applied Mathematical Department of BNUZ firstly, and the cooperation of senior professor and junior lecture in warm，selfless and enthusiastic environment. Certainly, it has very close relationship with the developing and open international education in BNUZ. Thank you all.
