Geometric examples accompany fundamental groups, homology and cohomology. A substantial first graduate text; 'introductory' refers to the field, not to university mathematics.
Preparation: Point-set topology; groups and rings.
Moves from integer arithmetic to rings, quadratic and cyclotomic examples, factorization, congruences and sums of squares. Later chapters are drafts or outlines.

Moves from integer arithmetic to rings, quadratic and cyclotomic examples, factorization, congruences and sums of squares. Later chapters are drafts or outlines.
Preparation: Proof-writing and elementary algebra; rings and fields are introduced in the notes.
Use: Connect elementary number theory with algebraic structures without treating unfinished later chapters as a complete advanced course.

Original title: 行列式入门
A book devoted to determinants, including their definitions, identities and methods of calculation. Use selected chapters alongside a linear-algebra course rather than replacing the whole course with determinant techniques.专门讨论行列式的定义、恒等式和计算方法。适合在线性代数课程中按需选读,不必将整门课程变成行列式技巧训练。
Preparation: School algebra and basic matrix operations.中学代数和基本矩阵运算。
Use: Consult the introductory chapters for definitions, then select the identities needed for a particular problem.先用开篇章节理解定义,再按具体问题查阅所需恒等式。
