An estimate of the gap of spectrum of Schrödinger operators which generate hyperbounded semigroup
Notations (X, B, m): Probability space dm ϕ = ϕ 2 dm: Weighted measure (ϕ ∈ L 2 (m)). V ∈ L 1 (X, m). u m = X udm In this section, we are working in more general situations than hyperbounded setting. (A1) (conservativeness and derivation property) P t : a conservative L 2-Markovian symmetric semigroup on L 2 (m). (E, D) : the corresponding Dirichlet form. Then E(1, 1) = 0 holds. For any ϕ which...
متن کاملExistence of the Spectral Gap for Elliptic Operators
Let M be a connected, noncompact, complete Riemannian manifold, consider the operator L = ∆+∇V for some V ∈ C(M) with exp[V ] integrable w.r.t. the Riemannian volume element. This paper studies the existence of the spectral gap of L. As a consequence of the main result, let ρ be the distance function from a point o, then the spectral gap exists provided limρ→∞ supLρ < 0 while the spectral gap d...
متن کاملInverse spectral problems for Sturm-Liouville operators with transmission conditions
Abstract: This paper deals with the boundary value problem involving the differential equation -y''+q(x)y=lambda y subject to the standard boundary conditions along with the following discontinuity conditions at a point y(a+0)=a1y(a-0), y'(a+0)=a2y'(a-0)+a3y(a-0). We develop the Hochestadt-Lieberman’s result for Sturm-Lio...
متن کاملSpectral Approximation for Compact Operators
In this paper a general spectral approximation theory is developed for compact operators on a Banach space. Results are obtained on the approximation of eigenvalues and generalized eigenvectors. These results are applied in a variety of situations.
متن کاملSpectral gap and coercivity estimates for linearized Boltzmann collision operators without angular cutoff
In this paper we prove new constructive coercivity estimates for the Boltzmann collision operator without cutoff, that is for long-range interactions. In particular we give a generalized sufficient condition for the existence of a spectral gap which involves both the growth behavior of the collision kernel at large relative velocities and its singular behavior at grazing and frontal collisions....
