The heat kernel can be represented as:
: Identifies linear operators that can be modeled as simple multiplication operators, often involving the diagonalization of matrices or operators. Geometric Applications
Spectral theory is a branch of functional analysis that deals with the study of linear operators on a Hilbert space. In the context of the heat kernel, spectral theory provides a framework for understanding the behavior of the heat kernel in terms of the eigenvalues and eigenfunctions of the Laplace operator.
The ( ) is the fundamental solution to the heat equation. In spectral theory, it acts as a bridge between a manifold's (or graph's) geometry and its spectrum (eigenvalues of the Laplacian). 1. Definition and Fundamental Equations
K(x,y,0) = δ(x-y)
The definitive text for second-order elliptic operators.
