Andrew Neitzke - Introduction to wall-crossing, in physics and differential equations
It has been known since the early 1990s that wall-crossing phenomena are crucial for understanding the spectrum of particles in supersymmetric quantum field theories. More recently, the rich algebraic and geometric structures underlying these phenomena are beginning to be understood. I wi
