Fredholm integral equations of the first kind and topological information theory
Enrico De Micheli, Giovanni Alberto Viano
The Fredholm integral equations of the first kind are a classical example of ill-posed problem in the sense of Hadamard. If the integral operator is self-adjoint and admits a set o…
Holomorphic extensions associated with series expansions
Enrico De Micheli, Giovanni Alberto Viano
We study the holomorphic extension associated with power series, i.e., the analytic continuation from the unit disk to the cut-plane . Analogous r…
Numerical recovery of location and residue of poles of meromorphic functions
Enrico De Micheli, Giovanni Alberto Viano
We present a method able to recover location and residue of poles of functions meromorphic in a half--plane from samples of the function on the real positive semi-axis. The functio…
Inverse optical imaging viewed as a backward channel communication problem
Enrico De Micheli, Giovanni Alberto Viano
The inverse problem in optics, which is closely related to the classical question of the resolving power, is reconsidered as a communication channel problem. The main result is the…
Transition from resonances to surface waves in pi^+-p elastic scattering
Enrico De Micheli, Giovanni Alberto Viano
In this article we study resonances and surface waves in --p scattering. We focus on the sequence whose spin-parity values are given by $J^p = {3/2}^+,{7/2}^+, {11/2}^+, {15/2…
Geometrical theory of diffracted rays, orbiting and complex rays
Enrico De Micheli, Giovanni Alberto Viano
In this article, the ray tracing method is studied beyond the classical geometrical theory. The trajectories are here regarded as geodesics in a Riemannian manifold, whose metric a…
