Inverse problem for Dirac systems with locally square-summable potentials and rectangular Weyl functions [PDF]

open access: yes, 2014
Inverse problem for Dirac systems with locally square summable potentials and rectangular Weyl functions is solved. For that purpose we use a new result on the linear similarity between operators from a subclass of triangular integral operators and the ...

E-Orbit Functions [PDF]

open access: yes, 2008
We review and further develop the theory of $E$-orbit functions. They are functions on the Euclidean space $E_n$ obtained from the multivariate exponential function by symmetrization by means of an even part $W_{e}$ of a Weyl group $W$, corresponding to ...

Analysis techniques for complex-field radiation pattern measurements [PDF]

open access: yes, 2018
Complex field measurements are increasingly becoming the standard for state-of-the-art astronomical instrumentation. Complex field measurements have been used to characterize a suite of ground, airborne, and space-based heterodyne receiver missions [1], [

Quantitative mixing results and inner functions [PDF]

open access: yes, 2006
19 pages, no figures.-- MSC2000 codes: 30D05, 30D50, 37A05, 37A25, 37F10, 28D05, 11K55.MR#: MR2262783 (2007j:37003)Zbl#: Zbl 1125.30019We study in this paper estimates on the size of the sets of points which are well approximated by orbits of other ...

Spin structure functions [PDF]

open access: yes, 1999
We review the study of the internal spin structure of the proton and neutron. High-energy scattering of polarized leptons by polarized protons, neutrons, and deuterons provides a measurement of the nucleon spin structure functions.

Hilbert Functions of Filtered Modules [PDF]

open access: yes, 2009
In this presentation we shall deal with some aspects of the theory of Hilbert functions of modules over local rings, and we intend to guide the reader along one of the possible routes through the last three decades of progress in this area of dynamic ...

Arithmetic theory of E-operators [PDF]

open access: yes, 2014
In [S\'eries Gevrey de type arithm\'etique I Th\'eor\'emes de puret\'e et de dualit\'e, Annals of Math. 151 (2000), 705--740], Andr\'e has introduced E-operators, a class of differential operators intimately related to E-functions, and constructed local ...

Holomorphic Functions and polynomial ideals on Banach spaces [PDF]

open access: yes, 2010
Given $\u$ a multiplicative sequence of polynomial ideals, we consider the associated algebra of holomorphic functions of bounded type, $H_{b\u}(E)$. We prove that, under very natural conditions verified by many usual classes of polynomials, the spectrum

Determination of fragmentation functions and their uncertainties from e+ + e- -> h + X data [PDF]

open access: yes, 2006
Fragmentation functions are determined for pions, kaons, and nucleons by a global analysis of charged-hadron production data in electron-positron annihilation.

Generalised Weber Functions [PDF]

open access: yes, 2013
A generalised Weber function is given by $\w_N(z) = \eta(z/N)/\eta(z)$, where $\eta(z)$ is the Dedekind function and $N$ is any integer; the original function corresponds to $N=2$.
