"The book comprises four well-organized chapters, each progressively building upon the previous ... . Each chapter is supplemented with examples, exercises, and concise proofs, reflecting the pedagogical origin of the text. The volume ends with a rich bibliography of 56 references. One of the book’s notable strengths is its clarity and brevity." (Gabriel Eduard Vilcu, zbMATH 1556.53001, 2025) “This book is called a concise introduction, and many topics are treated quickly. Some subjects are touched on only very briefly (cohomology classes and almost complex structures, for example), and probably deserve more detail and some examples. … This is an excellent introduction to the subject for those with sufficient background. It incorporates many topics in relatively few pages, but it is complete, rigorous and thorough.” (Bill Satzer, MAA Reviews, November 13, 2024)
