Lectures on the Orbit Method (Graduate Studies in Mathematics, Vol. 64) (Graduate Studies in Mathematics)

The notion of singularity is basic to mathematics. In algebraic geometry, the resolution of singularities by simple algebraic mappings is truly a fundamental problem. It has a complete solution in characteristic zero and partial solutions in arbitrary characteristic. The resolution of singularities in characteristic zero is a key result used in many subjects besides algebraic geometry, such as differential equations, dynamical systems, number theory, the theory of $\mathcal{D}$-modules, topology, and mathematical physics. This book is a rigorous, but instructional, look at resolutions.A simplified proof, based on canonical resolutions, is given in this book for characteristic zero. There are several proofs given for resolution of curves and surfaces in characteristic zero and arbitrary characteristic. Besides explaining the tools needed for understanding resolutions, Cutkosky explains the history and ideas, providing valuable insight and intuition for the novice (or expert). There are many examples and exercises throughout the text. The book is suitable for a second course on an exciting topic in algebraic geometry. A core course on resolutions is contained in Chapters 2 through 6. Additional topics are covered in the final chapters. The prerequisite is a course covering the basic notions of schemes and sheaves.

Isaac Newton encrypted his discoveries in analysis in the form of an anagram, which deciphers to the sentence “It is worthwhile to solve differential equations”. Accordingly, one can express the main idea behind the Orbit Method by saying'It is worthwhile to study coadjoint orbits'. The orbit method was introduced by the author, A. A. Kirillov, in the 1960s and remains a useful and powerful tool in areas such as Lie theory, group representations, integrable systems, complex and symplectic geometry, and mathematical physics. This book describes the essence of the orbit method for non-experts and gives the first systematic, detailed, and self-contained exposition of the method. It starts with a convenient “User's Guide” and contains numerous examples. It can be used as a text for a graduate course, as well as a handbook for non-experts and a reference book for research mathematicians and mathematical physicists. Ch. 1.

The orbit method is a useful tool in areas such as Lie theory, group representations, integrable systems, and mathematical physics. Kirillov, who introduced the orbit method in the 1960s, provides a self-contained exposition of the orbit method for non-experts. The book can be used as a text for a graduate course, a handbook for non- experts, and a reference for research mathematicians and mathematical physicists.
