AI 中文摘要
本文证明,对于每个p>2,在单位球面Sn(n≥2)上存在一个正密度的正交球谐函数子序列,该子序列达到最大的Lp范数增长。事实上,该密度可以任意接近1。这扩展了Han(arXiv:1404.5016)的结果到所有维数和所有p>2。
英文摘要
In this paper, we show that for every p>2, there is an orthonormal basis of spherical harmonics on Sn with n>=2 which achieves the maximal Lp norm growth. More precisely, one basis achieves this growth for all p<=2(n+1)/(n-1), and another for all p>=2(n+1)/(n-1). This extends the results in Han (arXiv:1404.5016) to all dimensions and all p>2, and improves the positive density subsequence there to a whole basis.
