WebDec 31, 2013 · This article is to analyze certain bounds for the sums of eigenvalues of the Dirichlet fractional Laplacian operator ( − Δ) α / 2 Ω restricted to a bounded domain Ω ⊂ R d with d = 2, 1 ≤ α ≤ 2 and d ≥ 3, 0 < α ≤ 2. A primary topic is the refinement of the Berezin-Li-Yau inequality for the fractional Laplacian eigenvalues. WebAug 9, 2024 · EVSL handles real symmetric standard eigenvalue problems and real symmetric generalized eigenvalue problems. Polynomial filtering is recommended mostly for cases where (1) matrix-vector operations are not too expensive and (2) the spectrum is not too irregularly distributed.
