Compression of Solar Spectroscopic Observations: a Case Study of Mg II k Spectral Line Profiles Observed by NASA's IRIS Satellite

Viacheslav M Sadykov, Irina N Kitiashvili, Alberto Sainz Dalda +3

In this study we extract the deep features and investigate the compression of the Mg II k spectral line profiles observed in quiet Sun regions by NASA's IRIS satellite. The data se…

Pontryagin algebras of some moment-angle-complexes

Yakov Veryovkin

We consider the problem of describing the Pontryagin algebra (loop homology) of moment-angle complexes and manifolds. The moment-angle complex Z_K is a cell complex built of produc…

Nonlinear stability of two-dimensional axisymmetric vortices in compressible inviscid medium in a rotating reference frame

Olga S. Rozanova, Jui-Ling Yu, Marko K. Turzynsky +1

We study the stability of the vortex in a 2D model of continuous compressible media in a uniformly rotating reference frame. As it is known, the axisymmetric vortex in a fixed refe…

On the uniqueness of solutions to continuity equations

V. I. Bogachev, G. Da Prato, M. Röckner +1

We obtain sufficient conditions for the uniqueness of solutions to the Cauchy problem for the continuity equation in classes of measures that need not be absolutely continuous.

A connection between filter stabilization and eddy viscosity models

Maxim A. Olshanskii, Xin Xiong

Recently, a new approach for the stabilization of the incompressible Navier-Stokes equations for higher Reynolds numbers was introduced based on the nonlinear differential filterin…

Hirzebruch genera of manifolds with torus action

Taras E. Panov

A quasitoric manifold is a smooth 2n-manifold M^{2n} with an action of the compact torus T^n such that the action is locally isomorphic to the standard action of T^n on C^n and the…

On nonformal simply connected symplectic manifolds

Ivan K. Babenko, Iskander A. Taimanov

For any nonformal simply connected symplectic manifolds of dimension are constructed. This disproves the formality conjecture for simply connected symplectic manifo…
