The Enigmatic Realm of Schur Functions and Affine Schubert Calculus
Schur functions and affine Schubert calculus form an intriguing field of study that holds immense significance in various branches of mathematics. In this article, we will delve into the depths of this captivating subject and explore the concepts, applications, and the wealth of knowledge encapsulated within the renowned Fields Institute Monographs 33.
What Are Schur Functions?
Schur functions, introduced by Issai Schur in the early 20th century, are a fundamental tool in algebraic combinatorics and representation theory. These functions appear in a wide range of mathematical theories, including symmetric functions, representation theory of the general linear group, and algebraic geometry.

One of the key properties of Schur functions is their association with Young tableaux, which are graphical representations of integer partitions. These tableaux provide a visual representation of the structure and symmetry of Schur functions, making them immensely valuable in various mathematical applications.
Affine Schubert Calculus: Unraveling the Complexity
Affine Schubert calculus, also known as Schubert calculus on the affine Grassmannian, is a branch of algebraic geometry that studies certain cohomology rings associated with flag varieties. Its development was heavily influenced by classical Schubert calculus, a well-established subfield of mathematics.
The affine Schubert calculus provides a fascinating perspective on various mathematical objects, including Schur functions. It aims to understand the structure and properties of Schubert varieties, which have deep connections to algebraic combinatorics and representation theory.

This book gives an to the very active field of combinatorics of affine Schubert calculus, explains the current state of the art, and states the current open problems. Affine Schubert calculus lies at the crossroads of combinatorics, geometry, and representation theory. Its modern development is motivated by two seemingly unrelated directions. One is the of k-Schur functions in the study of Macdonald polynomial positivity, a mostly combinatorial branch of symmetric function theory. The other direction is the study of the Schubert bases of the (co)homology of the affine Grassmannian, an algebro-topological formulation of a problem in enumerative geometry.
This is the first introductory text on this subject. It contains many examples in Sage, a free open source general purpose mathematical software system, to entice the reader to investigate the open problems. This book is written for advanced undergraduate and graduate students, as well as researchers, who want to become familiar with this fascinating new field.
