Nonnegative Low-Rank Matrix Correction under an Orthogonality Constraint in Conservative Vlasov Simulations
Yue Wu, Stephen Becker, Jingmei Qiu +1
The paper proposes optimization-based post‑processing methods to enforce nonnegativity on low‑rank approximations in conservative Vlasov simulations while exactly preserving densit…

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-Îu+(Q+\varepsilon V)u= A_{3,μ} \left(\int_Ω\f…
