On Dirichlet-to-Neumann Maps and Some Applications to Modified Fredholm Determinants,en sets with a compact, nonempty boundary ∂Ω satisfying certain regularity conditions. As an application we describe a reduction of a certain ratio of modified Fredholm perturbation determinants associated with operators in ..(Ω; ...) to modified Fredholm perturbation determinants associated with op

,Higher Derivatives of Spectral Functions Associated with One-Dimensional Schrödinger Operators,of one-dimensional Schrödinger operators on the half-line with integrable potentials. In particular, we identify sufficient conditions on the potential for the existence and continuity of the .th derivative, . . (λ), and outline a systematic procedure for estimating numerical upper bounds for the tu

,On the Schrödinger Operator with Limit-periodic Potential in Dimension Two, prove that the spectrum of . contains a semiaxis and there is a family of generalized eigenfunctions at every point of this semiaxis with the following properties. First, the eigenfunctions are close to plane waves e. at the high energy region. Second, the isoenergetic curves in the space of moment

Inverse Scattering Problem for a Special Class of Canonical Systems and Non-linear Fourier Integral sets (including Cantor sets of positive Lebesgue measure), however they did not take into account the mass point spectrum. This paper follows similar lines for the continuous setting with an absolutely continuous spectrum on the half-axis and a pure point spectrum on the negative half-axis satisfyi

On Some Properties of Infinite-dimensional Elliptic Coordinates,s to the infinite case has been offered. We consider this generalization and indicate the connection of infinite-dimensional elliptic coordinates with some inverse spectral problems for infinite Jacobi matrices and sturm-Liouville operators (two spectra inverse problems). Also a link with the rank o

Finite Difference Operators with a Finite-Band Spectrum,ization of the spectral curves in terms of, so-called, branching divisors. The multiplication operator by the covering map with respect to the natural basis in the Hardy space on the surface is the 2.+1-diagonal matrix; the .-root of the product of the Green functions (counting their multiplicities)

,Connections Between Dynamical Systems and Crossed Products of Banach Algebras by ℤ, where the latter act on . via iterations of σ. The automorphism induces a topological dynamical system on the character space Δ(.) of . in a natural way. We prove an equivalence between the property that every nonzero ideal in the crossed product has non-zero intersection with the subalgebra ., max

Monique Combescurees Thema. Finanzmathematik, üb- haupt Mathematik, ist schlichtweg unverständlich und eigentlich doch in jeder Hinsicht überflüssig – eine Art magische Geheimwissenschaft, bestehend aus zahlreichen Formeln, die sich niemand auf Dauer oder wenn, dann nur der eingeweihte Profi und Insider merken kann.
