Energy transfer between modes in a nonlinear beam equation
Ubertino Battisti, Elvise Berchio, Alberto Ferrero +1
We consider the nonlinear nonlocal beam evolution equation introduced by Woinowsky- Krieger. We study the existence and behavior of periodic solutions: these are called nonlinear m…
Stockwell-Like Frames for Sobolev Spaces
Ubertino Battisti, Michele Berra, Anita Tabacco
We construct a family of frames describing Sobolev norm and Sobolev seminorm of the space . Our work is inspired by the Discrete Orthonormal Stockwell Transform…
Explicit construction of non-stationary frames for
Ubertino Battisti, Michele Berra
We show the existence of a family of frames of which depend on a parameter . If , we recover the usual Gabor frame, if we obtain a frame sy…
Fourier Integral Operators of Boutet de Monvel Type
Ubertino Battisti, Sandro Coriasco, Elmar Schrohe
Given two compact manifolds with boundary and a boundary preserving symplectomorphism , which is one-homogeneous in the fibers and satisf…
On a Class of Fourier Integral Operators on Manifolds with Boundary
Ubertino Battisti, Sandro Coriasco, Elmar Schrohe
We study a class of Fourier integral operators on compact manifolds with boundary, associated with a natural class of symplectomorphisms, namely, those which preserve the boundary.…
Window-Dependent Bases for Efficient Representations of the Stockwell Transform
Ubertino Battisti, Luigi Riba
Since its appearing in 1996, the Stockwell transform (S-transform) has been applied to medical imaging, geophysics and signal processing in general. In this paper, we prove that th…
