MoirÃ©-modulated $I^$ valley in twisted bilayer and twisted double-bilayer MoTe $_{2}$

Wanying Chen, Hongyun Zhang, Jinxi Lu +18

Twisted MoTe $_{2}$ hosts intriguing correlated quantum phenomena including the fractional quantum anomalous Hall effect in twisted bilayer (t-BL) MoTe $_{2}$ near 3.7 $^{\circ}$ , which is…

Average Nikolskii factors for random trigonometric polynomials

Yun Ling, Jiaxin Geng, Jiansong Li +1

For $1 \leq p, q \leq \infty$ , the Nikolskii factor for a trigonometric polynomial $T_{a}$ is defined by $$\mathcal N_{p,q}(T_{\bf a})=\frac{\|T_{\bf a}\|_{q}}{\|T_{\bf a}\|_{p}},\…

Optimal quadrature for weighted function spaces on multivariate domains

Jiansong Li, Heping Wang

Consider the numerical integration $Int_{S^{d}, w} (f) = \int_{S^{d}} f (x) w (x) d I ¨ (x)$ for weighted Sobolev classes $B W_{p, w}^{r} (S^{d})$ …

Exact $L_{2}$ Bernstein-Markov inequalities for generalized weights

Jiansong Li, Jiaxin Geng, Yun Ling +1

In this paper, we obtain some exact $L_{2}$ Bernstein-Markov inequalities for generalized Hermite and Gegenbauer weight. More precisely, we determine the exact values of the extremal…
