Two people were shot, one fatally, Tuesday afternoon during a LaPlace business robbery. Three nearby schools went into lockdown mode, which was later lifted. The violence erupted at 2:36 p.m. at ...

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 ...

This paper describes an L1 regularized variational framework for developing a spatially localized basis, compressed plane waves, that spans the eigenspace of a differential operator, for instance, the ...

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 ...
