Polarizations on abelian subvarieties of principally polarized abelian varieties with dihedral group actions
(Springer, 2014)
For any n > 2 we study the group algebra decomposition of an ([n/2] + 1)- dimensional family of principally polarized abelian varieties of dimension n with an action of the dihedral group of order 2n. For any odd prime p, ...
Investigation of Ferroelectricity and Piezoelectricity in Polar and Non-polar Polymers
(2022-06-01)
An overview is presented of experimental investigations during two decades at the Polymer Group Prof. Bernhard Gross in Sao Carlos, Brazil, on the properties of piezoelectric polymers. The paper is focused on innovations ...
On a conjecture by Mbekhta about best approximation by polar factors
(American Mathematical Society, 2021-11)
The polar factor of a bounded operator acting on a Hilbert space is the unique partial isometry arising in the polar decomposition. It is well known that the polar factor might not be a best approximant to its associated ...
A model for the competition between political mono-polarization and bi-polarization
(American Institute of Physics, 2020-06)
We investigate the phenomena of political bi-polarization in a population of interacting agents by means of a generalized version of the model introduced by Vazquez et al. [Phys. Rev. E 101, 012101 (2020)] for the dynamics ...

3D radiative transfer of intrinsically polarized dust emission based on aligned aspherical grains
(Oxford University Pres, 2017)
(Sub-)millimetre observations of the polarized emission of aligned aspherical dust grains enable us to study the magnetic fields within protoplanetary disc. However, the interpretation of these observations is complex. One ...
