چکیده

In this work we establish sharp kernel conditions ensuring that the corresponding integral operators belong to Schatten-von Neumann classes. The are given in terms of spectral properties acting on kernel. As applications several criteria different types differential and their asymptotics settings: compact manifolds, lattices, domains Rn finite measure, for anharmonic oscillators. We also give examples settings sub-Riemannian contact strictly pseudo-convex CR (sub-)Laplacians Lie groups. Nous établissons dans cet article des critères optimaux sur noyaux pour assurer que les opérateurs integraux correspondants appartiennent à une classe de Neumann. Les sont donnés en propriétés espectrales d'opérateurs agissant le noyau. Comme application nous obtenons d'opératurs differentiels et leur asymptotique espectrale cadres : variétés compactes, reticles, domaines measure finie, d'oscillateurs anharmoniques. Nos donnos aussi quelques cadre sous-riemanniene contact, strictement pseudoconvexes, sous-laplaciens groupes compacts.

Lower Bounds for Eigenvalues of Schatten-von Neumann Operators

Let Sp be the Schatten-von Neumann ideal of compact operators equipped with the norm Np(·). For an A ∈ Sp (1 < p <∞), the inequality [ ∞ ∑ k=1 |Reλk(A)| ] 1 p + bp [ ∞ ∑ k=1 | Imλk(A)| ] 1 p ≥ Np(AR)− bpNp(AI) (bp = const. > 0) is derived, where λj(A) (j = 1, 2, . . . ) are the eigenvalues of A, AI = (A − A∗)/2i and AR = (A + A∗)/2. The suggested approach is based on some relations between the ...

Schur multiplier projections on the von Neumann-Schatten classes

For 1 ≤ p < ∞ let Cp denote the usual von Neumann-Schatten ideal of compact operators on 2. The standard basis of Cp is a conditional one and so it is of interest to be able to identify the sets of coordinates for which the corresponding projection is bounded. In this paper we survey and extend the known classes of bounded projections of this type. In particular we show that some recent results...

Continuity and Schatten–von Neumann Properties for Pseudo–Differential Operators and Toeplitz operators on Modulation Spaces

Let M (ω) be the modulation space with parameters p, q and weight function ω. We prove that if p1 = p2, q1 = q2, ω1 = ω0ω and ω2 = ω0, and ∂ a/ω0 ∈ L ∞ for all α, then the Ψdo at(x,D) : M p1,q1 (ω1) → M22 (ω2) is continuous. If instead a ∈ M p,q (ω) for appropriate p, q and ω, then we prove that the map here above is continuous, and if in addition pj = qj = 2, then we prove that at(x,D) is a Sc...

An Interesting Class of Operators with Unusual Schatten–von Neumann Behavior

We consider the class of integral operators Qφ on L (R+) of the form (Qφf)(x) = ∫ ∞ 0 φ(max{x, y})f(y)dy. We discuss necessary and sufficient conditions on φ to insure that Qφ is bounded, compact, or in the Schatten–von Neumann class Sp, 1 < p < ∞. We also give necessary and sufficient conditions for Qφ to be a finite rank operator. However, there is a kind of cut-off at p = 1, and for membersh...
