Kontsevich integral
The Kontsevich integral is a mathematical concept in the field of topology and algebraic geometry. It provides a way to associate a formal power series to a given knot or link, capturing its geometric properties. This integral is particularly significant because it generalizes the notion of knot invariants, which are quantities that remain unchanged under deformations of the knot.
Developed by Maxim Kontsevich in the 1990s, the Kontsevich integral uses techniques from graph theory and deformation quantization. It has applications in various areas, including string theory and quantum field theory, making it a vital tool for understanding the relationships between geometry and physics.
