Graph curvature and Laplacian operators form a vibrant area of research at the intersection of differential geometry and graph theory. The concept of graph curvature, inspired by classical Ricci ...
The higher spin Laplace operator has been constructed recently as the generalization of the Laplacian in higher spin theory. This acts on functions taking values in arbitrary irreducible ...
SIAM Journal on Numerical Analysis, Vol. 56, No. 3 (2018), pp. 1243-1272 (30 pages) In this work, we propose novel discretizations of the spectral fractional Laplacian on bounded domains based on the ...
