Bogdan Grechuk’s Theorems of the 21st Century is an unusual survey of 106 significant mathematical theorems proved during the first decade of the 21st century (2001–2010). Rather than concentrating on one branch of mathematics, Grechuk ranges across many fields, selecting results appearing in the Annals of Mathematics. The chapters are organized chronologically—one chapter for each year—and individual sections are largely independent.
The central achievement of the book is accessibility. Grechuk attempts to explain genuinely modern research mathematics while requiring as little specialized background as possible. A typical section begins with an intuitive discussion, elementary examples or a simplified problem; introduces the definitions that are actually needed; and gradually works toward a precise statement of the modern theorem.
For example, a discussion of additive number theory can begin with something as familiar as choosing coin denominations and representing integers as sums before moving toward the underlying mathematical result. This makes the book occupy an interesting middle ground between popular mathematics—which often avoids precise formulations—and conventional research surveys, which may assume years of graduate-level preparation.
The result is therefore less a textbook to be read sequentially than a guided tour of contemporary mathematics. Readers can choose individual theorems according to their interests and encounter areas far outside their normal specialization. Springer describes the intended readership broadly, and published reviews particularly recommend it to mathematically interested high-school and undergraduate students as well as more advanced mathematicians wishing to broaden their perspective.
For someone interested in seeing what mathematicians have actually accomplished recently—rather than studying only the classical mathematics that dominates textbooks—the book provides an especially attractive entry point.
Key takeaways
- 106 important theorems from 2001–2010 are presented, spanning a wide range of mathematics.
- The emphasis is on making research-level mathematics understandable with minimal prerequisites, without abandoning precise mathematical statements.
- Each section is essentially self-contained, so the book works very well for selective reading rather than cover-to-cover study.
- It is particularly valuable as a bridge between popular mathematics and professional mathematical literature, and as a source of topics for students looking beyond the standard curriculum.
