Daniele Bartolucci, Changfeng Gui, Aleks Jevnikar, Amir Moradifam

摘要:

我们得到了最近在[42]中引入的球覆盖不等式的一个奇异形式,适用于处理具有超调和权的奇异Liouville型问题。作为应用,我们导出了奇异平均场方程在球面和有界区域上解的唯一性结果,以及对已知结果的新的完备证明,如在[56]中首次建立的球面凸多胞体的唯一性.此外,我们得到了新的对称性结果的球形Onsager涡方程。

英文摘要:

We derive a singular version of the Sphere Covering Inequality which was recently introduced in [42], suitable for treating singular Liouville-type problems with superharmonic weights. As an application we deduce new uniqueness results for solutions of the singular mean field equation both on spheres and on bounded domains, as well as new self-contained proofs of previously known results, such as the uniqueness of spherical convex polytopes first established in [56]. Furthermore, we derive new symmetry results for the spherical Onsager vortex equation.
