Spatial-Homogeneity of Stable Solutions of Almost-Periodic Parabolic Equations with Concave Nonlinearity
Yi Wang, Jianwei Xiao, Dun Zhou
We study the spatial-homogeneity of stable solutions of almost-periodic parabolic equations. It is shown that if the nonlinearity satisfies a concave or convex condition, then any…

Low-Rank Matrix Approximations with Flip-Flop Spectrum-Revealing QR Factorization
Yuehua Feng, Jianwei Xiao, Ming Gu
We present Flip-Flop Spectrum-Revealing QR (Flip-Flop SRQR) factorization, a significantly faster and more reliable variant of the QLP factorization of Stewart, for low-rank matrix…
