The main results are as follows: the relations between local fractional integrated semigroups and the corresponding Cauchy problem, global fractional integrated semigroups and regularized semigroups are given; introduction of the notion of regularized resolvent families, and the generation theorem and analyticity criterions for regularized resolvent families are obtained; the spectral inclusions between fractional resolvent family and its generator, and the approximation for fractional resolvent families in the cases of generators approximation and fractional orders approximation; elliptic operators with variable coefficients generating fractional resolvent family on L^2 by using numerical range techniques; and the L^p theory for elliptic operators with real coefficients highest order are obtained by Sobolev''s inequalities and the a priori estimates for elliptic operators; and a kind of coercive differential operators generates fractional regularized resolvent family by applying the Fourier multiplier method, functional calculus and some basic properties of Mittag-Leffler functions.

主要结论是:给出了局部分数次积分半群和相应的Cauchy问题的关系以及分数次积分半群和正则半群的关系;引入了正则预解族的概念,并给出了其生成定理和解析生成法则;给出了分数次预解族与其生成元的谱包含关系,并研究了在生成元逼近和分数阶逼近两种情况下相应的预解族的逼近问题;利用数值域方法证明了具变系数的椭圆算子在L^2上生成分数次预解族;利用Sobolev不等式和椭圆算子的先验估计证明了具变系数的椭圆算子在其最高项系数为实数时在L^p上生成分数次预解族;运用Fourier乘子理论、泛函演算和Mittag-Leffler函数证明了一类强制微分算子可以生成分数次正则预解族,并给出了该预解族的范数估计。

Finally, in the third section, by constructing some functional which similar to the conservation law of evolution equation and the technical estimates, we prove that in the inviscid limit the solution of generalized derivative Ginzburg—Landau equation converges to the solution of derivative nonlinear Schrodinger equation correspondently in one-dimension; The existence of global smooth solution for a class of generalized derivative Ginzburg—Landau equation are proved in two-dimension, in some special case, we prove that the solution of GGL equation converges to the weak solution of derivative nonlinear Schr〓dinger equation; In general case, by using some integral identities of solution for generalized Ginzburg—Landau equations with inhomogeneous boundary condition and the estimates for the L〓 norm on boundary of normal derivative and H〓 norm of solution, we prove the existence of global weak solution of the inhomogeneous boundary value problem for generalized Ginzburg—Landau equations.

第三部分:在一维情形,我们考虑了一类带导数项的Ginzburg—Landau方程,通过构造一些类似于发展方程守恒律的泛函及巧妙的积分估计,证明了当粘性系数趋于零时,Ginzburg—Landau方程的解逼近相应的带导数项的Schr〓dinger方程的解,并给出了最优收敛速度估计;在二维情形,我们证明了一类带导数项的广义Ginzburg—Landau方程整体光滑解的存在性,以及在某种特殊情形下,GL方程的解趋近于相应的带导数项的Schr〓dinger方程的弱解;在一般情形下,我们讨论了一类Ginzburg—Landau方程的非齐次边值问题,通过几个积分恒等式,同时估计解的H〓模及法向导数在边界上的模,证明了整体弱解的存在性。

A new method that introduces the new free-weighting matrices is proposed to estimate the upper bound of the derivative of the Lyapunov function by considering the additional useful terms which are ignored in previous methods.

新方法考虑一些以前方法中通常忽略的有用的项,引入一些自由权重矩阵,估计Lyapunov泛函导数的上界;再用凸优化算法,进一步给出状态反馈控制器的设计方法。

We discuss a class of second order self-adjoint matrix differential systems with damping term and self-adjoint Hamiltonian matrix differential systems, etc.

在第五、六章中,考虑一类线性泛函g和一类对s偏导数不一定非正的Hk型函数,分别研究了自伴的带有阻尼项的二阶矩阵微分系统和自共轭的Hamilton矩阵微分系统。

Miss Tsai Han-chieh presented the second report on Opening skinner's box . The author of the book was Lauren Slater. It introduced several classic experiments conducted by scholars of behavior psychology, including classical conditioning by Pavlov and operant conditioning by Skinner. Skinner held the opinion that human behavior is the result of environmental forces. He did not believe in free will of human beings. This had caused great controversy.

第二场由蔡函洁小姐报告《打开史金纳的箱子》,作者为Lauren Slater,介绍心理学行为学派学家所进行的数项经典实验,包括Pavlov的古典制约与Skinner的操作制约;而Skinner认为人类的行为是环境影响下的结果,否认人类具有自由意志,引发不小的争议。
