Blow-up asymptotics for a critical Hartree-type Brézis--Nirenberg problem in dimension three
Yue Wu, Minbo Yang
In this paper, we study the following critical Hartree problem \begin{equation}\label{equationabstract} \begin{cases} \displaystyle-Δu+(Q+\varepsilon V)u= A_{3,μ} \left(\int_Ω\frac…

Nonnegative Low-Rank Matrix Correction under an Orthogonality Constraint in Conservative Vlasov Simulations
Yue Wu, Stephen Becker, Jingmei Qiu +1
In low-rank numerical methods for Vlasov dynamics, the SVD-type truncation procedure may introduce negative entries into the numerical solution. Such negative values are unphysical…
