An Introduction to Heisenberg Groups in Analysis and Geometry
Stephen Semmes
This article discusses some aspects of Heisenberg groups and the ways in which their algebraic structure is reflected in Fourier analysis, complex analysis, and geometry.
The Moduli Space of Curves and Its Tautological Ring
Ravi Vakil
The moduli space of curves plays a key role in algebraic geometry. This article focuses on the so-called tautological ring, emphasizing its combinatorial structure.
