Null-vectors in Integrable Field Theory [PDF]

, 1997
The form factor bootstrap approach allows to construct the space of local fields in the massive restricted sine-Gordon model. This space has to be isomorphic to that of the corresponding minimal model of conformal field theory.

Fredholm-Lagrangian-Grassmannian and the Maslov index [PDF]

, 2003
We explain the topology of the space, so called, Fredholm-Lagrangian-Grassmannain and the quantity ``Maslov index'' for paths in this space based on the standard theory of Functional Analysis.

Interpolation of the measure of non-compactness of bilinear operators among quasi-Banach spaces [PDF]

Journal of Approximation Theory, 2019
Working in the setting of quasi-Banach couples, we establish a formula for the measure of non-compactness of bilinear operators interpolated by the general real method. The result applies to the real method and to the real method with a function parameter.

A Unified Framework with Dynamic Kernel Learning for Bidirectional Feature Resampling in Remote Sensing Images

Remote Sensing
The inherent multiscale nature of objects poses a fundamental challenge in remote sensing object detection. To address this, feature pyramids have been widely adopted as a key architectural component.

Metrics and spectral triples for Dirichlet and resistance forms [PDF]

, 2013
The article deals with intrinsic metrics, Dirac operators and spectral triples induced by regular Dirichlet and resistance forms. We show, in particular, that if a local resistance form is given and the space is compact in resistance metric, then the ...

Compact bilinear operators and paraproducts revisited

Canadian Mathematical Bulletin
AbstractWe present a new proof of the compactness of bilinear paraproducts with CMO symbols. By drawing an analogy to compact linear operators, we first explore further properties of compact bilinear operators on Banach spaces and present examples. We then prove compactness of bilinear paraproducts with CMO symbols by combining one of the properties of

Characterization of compactness of commutators of bilinear singular integral operators

Proceedings of the American Mathematical Society, 2018
The commutators of bilinear Calderón–Zygmund operators and pointwise multiplication with a symbol in C M O \mathrm {CMO} are bilinear compact operators on products of Lebesgue spaces. We show that, for certain non-degenerate Calderón–Zygmund operators, the symbol being in C M O

On the Kleinman-Martin integral equation method for electromagnetic scattering by a dielectric body

, 2011
The interface problem describing the scattering of time-harmonic electromagnetic waves by a dielectric body is often formulated as a pair of coupled boundary integral equations for the electric and magnetic current densities on the interface $\Gamma$. In
