双环化合物是天然产物和药物分子中的优势核心骨架,合成这些分子面临的挑战是如何高效地构建目标分子中的环系骨架。考虑最终产物中要去除金属杂质的困难性,有机催化的合成双环化合物方法是一个有效的途径。有机膦催化的Domino反应是一个构筑各种环状化合物的有效平台,主要用在单环的合成,我们发现联烯可以作为新的1,2,3-C3和1,2,4-C3合成子,通过底物调控,催化剂调控,催化模式调控可以实现目标产物的调
I will discuss some recent development of hybridization of high order nonlinear WENO FD scheme and classical linear scheme(finite differences,compact)and non-classical scheme(spectral,Fourier continua
In this talk,I will report our recent work of a class of central compact schemes with spectral-like resolution.Combining the technique of Lele s linear compact scheme and WENO interpolation,we develop
This talk focuses on discrete double/single-curl operators in Maxwells equations for 3D photonic crystals,chiral and pseudochiral complex media with face centered cubic lattices.
We consider nonstandard Petrov–Galerkin discretizations of linear problems in Banach spaces.
In the report the problems on stability and stabilization of nonlinear systems with aftereffect is investigated using Lyapunov functionals and nonstationary comparison systems.
In the report the problem of stabilization of nonlinear time-varying dynamical systems with digital control is investigated using Lyapunov vestor functions and comparison systems.
For the example the mathematical model of the flow channel with an elastic element on the wall is proposed.The model represents an initialboundary value problem for system of the differential equation
In this talk,the global dynamics of small smooth solutions to initialboundary value problems of the full compressible Euler equations with frictional damping,and a reduced system consisting of a porou
In the first part of this talk,the global well-posedness of strong solutions to an initial-boundary value problem of one-dimensional compressible heat-conductive MHD equaitons with constant viscosity,
