围绕财经特色主题加强《高等代数》精品课程建设

我校精品课程《高等代数》建设的思路是,围绕财经特色主题,坚持以高等代数理论为基础,以经济、管理类的专业为依托,以数学实验室为训练基地,将数学建模的思想融入到《高等代数》的教学活动中.这种教学模式的改变不仅有利于学生的培养,而且有助于培养出一支有较高水平的师资队伍.使我们的《高等代数》课程真正成为高水平、高质量的示范性课程.     

为什么要提倡数学建模,怎样教学生学习数学建模

在高中数学课程中倡导数学建模,是为了推动应用数学的观念在高中数学课程中扎根,并让它在学生心中发芽,让学生更好地理解数学与现实世界之间的联系.拉近数学教育的目标与数学的实用性之间的距离.在这样的思想指导下,我们对如何教学生会有一个不同的看法,数学教育的风格需要有一个变化,即向应用和实践的角度倾斜。单纯纠结数学建模课如何上,有可能使我们偏离更主要的目标.     

关于高等代数课程教学改革和教学实践的几点体会

高等代数是大学本科数学专业一门重要的基础课程,但由于该课程的内容、思想的抽象性,传统的教学模式很难使大一的学生入门,也很难培养学生对高等代数的兴趣.若将其与解析几何、数学软件、数学建模等结合起来,并将其内容的先后顺序做适当的调整,能使其内容具体化、生动化.更易适应大一新生的学习方式.切实培养大学生的数学素质,提高教学质量.     

提升学生直观想象素养的向量教学

<正>向量既是代数研究对象,也是几何研究对象,是沟通几何与代数的桥梁.向量教学应突出几何直观与代数运算之间的融合,即通过形与数的结合,感悟数学之间的关联,加强数学整体性理解^[1],重点提升学生的直观想象素养.本文结合向量教学中直观想象素养提升的实践,谈一谈对直观想象的理解和在课堂实践中得到启示,供同行研讨.     

感受有理数中的思想方法

<正>数学思想方法是数学学科的精髓,它蕴含在数学知识中,只有领悟了数学思想方法,才能真正体会数学的奥妙,才能触摸到数学的灵魂.掌握数学思想方法,有助于学生形成数学素养,在学习“有理数”时,主要有下面一些数学思想方法.1 数形结合思想借助数形结合思想,能达到形象地理解、认识、处理代数问题的目的.我国著名数学家华罗庚曾说：“数缺形时少直观,形无数时难入微,数形结合百般好,隔离分家万事休.”在数学中,数与形是我们主要的研究对象,

高中数学建模活动设计例谈

在最新的《普通高中数学课程标准（实验）》中指出：数学建模现已成为不同层次数学教育重要和基本内容,在高中阶段至少应为学生安排一次数学建模活动,应将课内和课外有机地结合起来。以研究性学习为载体,结合生活中的数学,深入开展高中数学建模活动,让学生认识和理解数学建模的理论和思想,有助于学生掌握扎实的数学基础知识,提高数学应用意识．笔者选择了两例生活中的数学,进行数学建模活动的设计,试图为数学建模活动在高中开展提供一条探索的途径．     

在高等代数教学中渗透数学史知识的思考

高等代数是一门内容丰富、思想独特、方法技巧较强的一门基础课程.在授课过程中,适当地渗透数学史知识,有助于学生兴趣的培养,有助于学生理解数学的思想、方法和精神,有助于培养他们抽象思维能力、逻辑推理能力、分析问题和解决问题能力.     

挖掘复习主线 提升核心素养——以高三数学微专题“任意性与存在性”的复习为例

"主线"在《普通高中数学课程标准(2017年版)》(以下简称《标准》)中并不是一个高频词,只出现了25次,但仔细品读《标准》会发现,恰恰是"主线"一词体现了本次课程在内容结构的重大变化.《标准》中的"主线"一词含义有二:一是"内容主线",《标准》突出了"函数、几何与代数、概率与统计,数学建模活动与数学探究活动"四条主线,这些内容,是学生进入社会应用需求和进一步学习最主要的基础,是提高学生核心素养的基本载体,是促进学生的思维能力、实践能力和创新意识发展的基本工具;二是"目标主线",高中数学课程的目标之一是"在学习数学和应用数学的过程中,学生能发展数学抽象、逻辑推理、数学建模、直观想象、数学运算、数据分析等数学学科核心素养."     

A REPRESENTATION FORMULA RELATED TO SCHR(O)DINGER OPERATORS

Schr(o)dinger operator is a central subject in the mathematical study of quantum mechanics.Consider the Schrodinger operator H = -△ V on R, where △ = d2/dx2 and the potential function V is real valued. In Fourier analysis, it is well-known that a square integrable function admits an expansion with exponentials as eigenfunctions of -△. A natural conjecture is that an L2 function admits a similar expansion in terms of "eigenfunctions" of H, a perturbation of the Laplacian (see [7], Ch. Ⅺ and the notes), under certain condition on V.     

On a class of self-similar processes with stationary increments in higher order Wiener chaoses

We study a class of self-similar processes with stationary increments belonging to higher order Wiener chaoses which are similar to Hermite processes. We obtain an almost sure wavelet-like expansion of these processes. This allows us to compute the pointwise and local Hölder regularity of sample paths and to analyse their behaviour at infinity. We also provide some results on the Hausdorff dimension of the range and graphs of multidimensional anisotropic self-similar processes with stationary increments defined by multiple Wiener–Itô integrals.     

Qualitative Analysis of Bifurcating Solutions in the Lengyel-Epstein Model

One of the most fundamental problems in theoretical biology is to explain the mechanisms by which patterns and forms are created in the＇living world. In his seminal paper ＂The Chemical Basis of Morphogenesis＂, Turing showed that a system of coupled reaction-diffusion equations can be used to describe patterns and forms in biological systems. However, the first experimental evidence to the Turing patterns was observed by De Kepper and her associates（1990） on the CIMA reaction in an open unstirred reactor, almost 40 years after Turing＇s prediction. Lengyel and Epstein characterized this famous experiment using a system of reaction-diffusion equations. The Lengyel-Epstein model is in the form as follows     

(0,1 ;0)-INTERPOLATION ON INFINITE INTERVAL (-∞, +∞)

In this paper, we study the explicit representation and convergence of (0, 1; 0)-interpolation on infinite interval, which means to determine a polynomial of degree ≤ 3n - 2 when the function values are prescribed at two set of points namely the zeros of Hn(x) and H′n(x) and the first derivatives at the zeros of H′n(x).     

On a class of Riemann surfaces

It is considered the class of Riemann surfaces with dimT1 = 0, where T1 is a subclass of exact harmonic forms which is one of the factors in the orthogonal decomposition of the spaceΩH of harmonic forms of the surface, namely The surfaces in the class OHD and the class of planar surfaces satisfy dimT1 = 0. A.Pfluger posed the question whether there might exist other surfaces outside those two classes. Here it is shown that in the case of finite genus g, we should look for a surface S with dimT1 = 0 among the surfaces of the form Sg\K , where Sg is a closed surface of genus g and K a compact set of positive harmonic measure with perfect components and very irregular boundary.

Staircase transportation problems with superadditive rewards and cumulative capacities

A cumulative-capacitated transportation problem is studied. The supply nodes and demand nodes are each chains. Shipments from a supply node to a demand node are possible only if the pair lies in a sublattice, or equivalently, in a staircase disjoint union of rectangles, of the product of the two chains. There are (lattice) superadditive upper bounds on the cumulative flows in all leading subrectangles of each rectangle. It is shown that there is a greatest cumulative flow formed by the natural generalization of the South-West Corner Rule that respects cumulative-flow capacities; it has maximum reward when the rewards are (lattice) superadditive; it is integer if the supplies, demands and capacities are integer; and it can be calculated myopically in linear time. The result is specialized to earlier work of Hoeffding (1940), Fréchet (1951), Lorentz (1953), Hoffman (1963) and Barnes and Hoffman (1985). Applications are given to extreme constrained bivariate distributions, optimal distribution with limited one-way product substitution and, generalizing results of Derman and Klein (1958), optimal sales with age-dependent rewards and capacities.To our friend, Philip Wolfe, with admiration and affection, on the occasion of his 65th birthday.Research was supported respectively by the IBM T.J.
