<p style='text-indent:20px;'>We prove global in time dispersion for the wave and Klein-Gordon equation inside Friedlander domain by taking full advantage of space-time localization caustics a precise estimate number waves that may cross at given, large time. Moreover, we uncover significant difference between low frequency, regime, where exhibits worse decay than wave, unlike flat space.&...

We prove interlacing inequalities between spectral minimal energies of metric graphs built on Dirichlet and standard Laplacian eigenvalues, as recently introduced in [Kennedy et al, arXiv:2005.01126]. These inequalities, which involve the first Betti number degree one vertices graph, recall both other for eigenvalues whole well estimates difference nodal Neumann domains graph eigenfunctions. To...

We prove quantitative nonvanishing theorems for central values and central derivatives of L–series associated to canonical Hecke characters of imaginary quadratic fields. These results have applications to the study of Chow groups of Kuga-Sato varieties. Some key ingredients in the proofs are bounds for `-torsion in class groups obtained recently by Ellenberg and Venkatesh [EV], and subconvexit...

We simulate the sintering of particle aggregates due to surface diffusion. As a method we use Kinetic Monte-Carlo simulations in which elasticity can explicitly be taken into account. Therefore it is possible to investigate the shape relaxation of aggregates also under the influence of an external pressure. Without elasticity we investigate the relaxation time and surface evolution of sintering...

In the late 1980s, Friedlander and Parshall studied representations of a family algebras which were obtained as deformations distribution algebra first Frobenius kernel an algebraic group. The representation theory these tells us much about Lie in positive characteristic. We develop analogue this for higher kernels, answering 30 year old question posed by Parshall. also examine their case speci...
