Summary
The text discusses Grassmannian calculus and its applications to probability, particularly in the context of uniform spanning trees and the Abelian sandpile model.
Highlights
- Grassmannian calculus is a mathematical framework that can be used to study systems with both bosonic and fermionic components.
- The Abelian sandpile model is a type of cellular automaton that exhibits self-organized criticality.
- The uniform spanning tree is a probability measure on the set of all spanning trees of a graph.
- Grassmannian calculus can be used to compute edge probabilities in the uniform spanning tree.
- The transfer-impedance matrix is a key object in the study of uniform spanning trees.
- Supersymmetry is a concept that combines bosonic and fermionic variables in a single framework.
- The supergaussian measure is a probability measure that combines Gaussian and Grassmannian variables.
