چکیده
We study the inverse scattering problem of determining a magnetic field and electric potential from measurements corresponding to finitely many plane waves. The main result shows that coefficients are uniquely determined by $2n$ up natural gauge. also show one can recover full first order term for related equation having no gauge invariance, it is possible reduce number if have certain symmetries. This work extends fixed angle results Rakesh M. Salo Hamiltonians with perturbations, based on wave methods Carleman estimates.

Inverse scattering problem with fixed energy and fixed incident direction
Let A q (α ′ , α, k) be the scattering amplitude, corresponding to a local potential q(x), x ∈ R 3 , q(x) = 0 for |x| > a, where a > 0 is a fixed number, α ′ , α ∈ S 2 are unit vectors, S 2 is the unit sphere in R 3 , α is the direction of the incident wave, k 2 > 0 is the energy. We prove that given an arbitrary function f (α ′) ∈ L 2 (S 2), an arbitrary fixed α 0 ∈ S 2 , an arbitrary fixed k ...
متن کاملINVESTIGATION OF BOUNDARY LAYERS IN A SINGULAR PERTURBATION PROBLEM INCLUDING A 4TH ORDER ORDINARY DIFFERENTIAL EQUATIONS
In this paper, we investigate a singular perturbation problem including a fourth order O.D.E. with general linear boundary conditions. Firstly, we obtain the necessary conditions of solution of O.D.E. by making use of fundamental solution, then by compatibility of these conditions with boundary conditions, we determine that, for given perturbation problem, whether boundary layer is formed or not.
متن کاملInverse scattering problem for the Impulsive Schrodinger equation with a polynomial spectral dependence in the potential
In the present work, under some di¤erentiability conditions on the potential functions , we rst reduce the inverse scattering problem (ISP) for the polynomial pencil of the Scroedinger equation to the corresponding ISP for the generalized matrix Scrödinger equation . Then ISP will be solved in analogy of the Marchenko method. We aim to establish an e¤ective algorithm for uniquely reconstructin...
متن کاملOn the Boundary Value Problem in a Dihedral Angle for Normally Hyperbolic Systems of First Order
Some structural properties as well as a general threedimensional boundary value problem for normally hyperbolic systems of partial differential equations of first order are studied. A condition is given which enables one to reduce the system under consideration to a first-order system with the spliced principal part. It is shown that the initial problem is correct in a certain class of function...
متن کاملThe Connection between Regge Behavior and Fixed Angle Scattering
The physical origins and dynamical details of Regge behavior are studied by examining a general class of theories which are capable of describing the observed large momentum transfer data and extending them into the intermediate t-range. The mechanism responsible for the smooth connection between the deep scattering region and the Regge region is discussed in detail. We derive a convenient new ...
