Harnack inequality for $p$ -harmonic functions: improved dimension dependence via tug of war

Yuval Peres, Han Wang

Let $p > 1$ . The Harnack inequality and HÃ¶lder continuity for $p$ -harmonic functions in bounded domains in $R^{d}$ are usually proved via Moser iteration. In 2013 Luiro, Parv…

Quantitative estimates of the spectral norm of random matrices with independent columns

Guozheng Dai, Zhonggen Su, Hanchao Wang

This paper investigates the nonasymptotic properties of the spectral norm of some random matrices with independent columns. In particular, we consider an $m \times n$ random matrix…
