We give a p-adic analogue of Selberg's trace formula relating the trace of a semigroup generated by a natural elliptic operator with a sum over contributions coming from closed geodesics. The construction uses probabilistic methods to define the generator. 相似文献

In this paper, we give a survey on the Hill-type formula and its applications.Moreover, we generalize the Hill-type formula for linear Hamiltonian systems and Sturm-Liouville systems with any self-adjoint boundary conditions, which include the standard Neumann, Dirichlet and periodic boundary conditions. The Hill-type formula connects the infinite determinant of the Hessian of the action functional with the determinant of matrices which depend on the monodromy matrix and boundary conditions. Further, based on the Hill-type formula, we derive the Krein-type trace formula. As applications, we give nontrivial estimations for the eigenvalue problem and the relative Morse index. 相似文献

We prove that the explicit formula in a symmetric case for a triple (Z,
[(Z)\tilde]\tilde{Z}
, Φ) in Jorgenson-Lang’s fundamental class of functions holds for a larger class of (not necessarily differentiable or even
continuous) test functions. As one of the most important applications, we show that the Selberg trace formula for a strictly
hyperbolic cocompact Fuchsian group Γ is valid for a larger class of test functions. Further applications to growth estimates
for the logarithmic derivative of the Selberg zeta function are considered. 相似文献

In a previous paper for a class of pairs of operators in a Hilbert space with nuclear difference or under a more general nuclearity condition there was introduced a spectral shift functional. Here we consider the local integrability of this spectral shift functional, i.e., the problem when this functional can locally be represented by an integrable function. The general results are then applied to pairs of definitizable and locally definitizable unitary operators in a Krein space. 相似文献

Spectrum properties and a method for deriving a regularized trace formula for perturbations of operators with discrete spectra in a separable Hilbert space are studied. A trace formula for a local perturbation of a two-dimensional harmonic oscillator in a strip is obtained based on this method. 相似文献

In this paper we establish a determinant formula
for a pair of unbounded self-adjoint operators u and v satisfying a commutation relation
where D is in the trace class, and some other condition. The functions f and g are rational functions satisfying certain condition. 相似文献

A new orthogonality relation for normed linear spaces is introduced using a concept of area of a parallelogram given by E. Silverman. Comparisons are drawn between this relation and an earlier relation used by G. Birkhoff. In addition, this new relation is utilized to obtain new characterizations of inner-product spaces. 相似文献

We consider compact metric graphs with an arbitrary self adjoint realisation of the differential Laplacian. After discussing
spectral properties of Laplacians, we prove several versions of trace formulae, relating Laplace spectra to sums over periodic
orbits on the graph. This includes trace formulae with, respectively, absolutely and conditionally convergent periodic orbit
sums; the convergence depending on properties of the test functions used. We also prove a trace formula for the heat kernel
and provide small-t asymptotics for the trace of the heat kernel.
