WebToward a Spectral Theory of Cellular Sheaves - CORE Reader WebExample. The simplest cellular sheaf is the constant sheaf with stalk a given vector space V . This is the sheaf with every stalk equal to V , and every restriction map the identity. We denote this sheaf V . The global sections of V are the locally constant V -valued functions on G , i.e., those which are constant on every connected component ...

Toward a Spectral Theory of Cellular Sheaves

WebThis paper outlines a program in what one might call spectral sheaf theory --- an extension of spectral graph theory to cellular sheaves. By lifting the combinatorial graph Laplacian to the Hodge Laplacian on a cellular sheaf of vector spaces over a regular cell complex, one can relate spectral data to the sheaf cohomology and cell structure in a manner … WebEnter the email address you signed up with and we'll email you a reset link.
