1. Six new species of Stenometopiini (Hemiptera: Cicadellidae: Deltocephalinae) with redescription of additional species and new distributional records

   https://doi.org/10.11646/zootaxa.4603.2.1  

   DUAN, YANI; ZHANG, YATING; DIETRICH, CHRISTOPHER H. (May 2019, Zootaxa)

   Six new species of Stenometopiini are described: Stirellus paracatalinus sp. nov. from Mexico, Stirellus lesioensis sp. nov. from Republic of Congo, Stirellus paralesioensis sp. nov. from South Africa, Stirellus kitwensis sp. nov. from Zambia, Stirellus madagascarensis sp. nov. from Madagascar, and Stirellus petfordensis sp. nov. from Australia. Ten species are redescribed: Kinonia elongata Ball, Stirellus catalinus (Beamer & Tuthill), Stirellus labiatus (Gillette), Stirellus mexicanus (Osborn & Ball), Stirellus picinus (Berg), Stirellus laetus (Melichar), Stirellus multipunctatus Duan, Webb & Zhang, Stirellus neospeciosus Duan, Webb & Zhang, Stirellus rubrolineatus (Distant), and Stirellus sagittarius (Naudé). Kinonia elongata Ball, S. catalinus (Beamer & Tuthill) and S. labiatus (Gillette), all described from the Southwestern USA, are recorded from Mexico for the first time. Stirellus picinus (Berg) is recorded from the Virgin Islands (Guana Island) for the first time. Stirellus laetus (Melichar), S. multipunctatus Duan, Webb & Zhang, S. neospeciosus Duan, Webb & Zhang, and S. rubrolineatus (Distant) are recorded from Thailand for the first time.

3. A higher dimensional Bourgain-Dyatlov fractal uncertainty principle

   Han, Rui; Schlag, Wilhelm (October 2019, Analysis & PDE)

   We establish a version of the fractal uncertainty principle, obtained by Bourgain and Dyatlov in 2016, in higher dimensions. The Fourier support is limited to sets Y⊂ℝd which can be covered by finitely many products of δ-regular sets in one dimension, but relative to arbitrary axes. Our results remain true if Y is distorted by diffeomorphisms. Our method combines the original approach by Bourgain and Dyatlov, in the more quantitative 2017 rendition by Jin and Zhang, with Cartan set techniques.

4. On convergence criteria for the coupled flow of Li–Yuan–Zhang

   Fei, Teng; Guo, Bin; Phong, Duong H. (March 2019, Mathematische Zeitschrift)

   A one-parameter family of coupled flows depending on a parameter $$\kappa>0$$ is introduced which reduces when $$\kappa=1$$ to the coupled flow of a metric $$\omega$$ with a $(1,1)$-form $$\alpha$$ due recently to Y. Li, Y. Yuan, and Y. Zhang. It is shown in particular that, for $$\kappa\not=1$$, estimates for derivatives of all orders would follow from $C^0$ estimates for $$\omega$$ and $$\alpha$$. Together with the monotonicity of suitably adapted energy functionals, this can be applied to establish the convergence of the flow in some situations, including on Riemann surfaces. Very little is known as yet about the monotonicity and convergence of flows in presence of couplings, and conditions such as $$\kappa\not=1$$ seem new and may be useful in the future.
