Bolzano's Theorems for Holomorphic Mappings(To Ham Brezis,with friendship and admiration)

引用

Chinese Annals of Mathematics,Series B 2017年第2期38卷 563-578页

作者： jean MAWHIN institut de recherche en mathématique et physique universitécatholique de louvain chemin du cyclotron2 1348 Louvain-la-NeuveBelgium

The existence of a zero for a holomorphic functions on a ball or on a rectangle under some sign conditions on the boundary generalizing Bolzano's ones for real functions on an interval is deduced in a very simple way from Cauchy's theorem for holomorphic functions. A more complicated proof, using Cauchy's argument principle, provides uniqueness of the zero, when the sign conditions on the boundary are strict. Applications are given to corresponding Brouwer fixed point theorems for holomorphic functions. Extensions to holomorphic mappings from C^n to C^n are obtained using Brouwer degree.

This article focuses on the study of crushing rocks that can replace clinker in low-carbon cement. A laboratory ball mill was used, varying the duration of the grinding. It has been observed that the specific surface of rocks changes in a nonlinear way with time, due to the agglomeration of particles. To this end, a mathematical model describing this evolution, which considers van der Waals forces, has been proposed. And finally, the model was adjusted regarding the experimental data. The results found show that the present model is more accurate than the classical models, because it considers the agglomeration phenomenon.

Design and Modeling of Electromagnetic Impedance Surfaces to Reduce Coupling between Antennas

引用

Wireless Engineering and Technology 2012年第3期3卷 152-159页

We study the coupling problem of two waveguide antennas using the design of a two-dimensional inhomogeneous impedance structure with a fixed reflected field. Since this structure enables electromagnetic compatibility between antennas located on a plane, the behaviors of the electromagnetic field along the impedance structure are investigated. The method of moments is used to solve the integral equations and the numerical results are presented and analyzed. To reduce coupling between antennas, we need to take into account both the amplitude distribution of the field along the structure and in the openings of the antennas. In addition, while designing the structure, it is necessary to control the coefficient of decoupling.

华南地块陡山沱组的古地磁和C同位素研究揭示了其形成于赤道附近的古地理环境。对冰期后的盖帽白云岩的C同位素研究表明,δ13C从-5‰开始有缓慢升高的趋势,与世界上Marinoan冰期其他剖面的C同位素变化相一致。陡山沱期大气中CO2含量的升高可能与Rodinia超大陆的裂解及火山活动等密切相关。
