数学交流浅谈

数学交流 ,是运用表达数学概念、关系、方法、问题、思想的语言与情感的过程 .从数学的社会性来讲 ,数学思想只有被“数学共同体”所接受才能算是正确的 .因此 ,在数学教学中 ,为了对数学知识作出解释 ,教师必须用数学语言符号 ,同时学生也必须理解这些语言符号 ,于是就存在一个数学学习共同体成员之间彼此解释各自的想法、相互理解对方思想的问题 .因此 ,数学教学就是共同体成员之间所进行的讨论交流活动 .1　“数学交流”探源　在数学教育领域 ,较早提出“数学交流”的是1981年英国“学校数学调查委员会”向政府提交的《Ｃｏｃｋｏｒｏｆ…     

强化数学实验教学，提高应用数学能力

Didactics of mathematics as a scientific discipline: A sketch of its development from a personal (autobiographic) point of view

At the 8th International Congress on Mathematical Education (ICME-8) held in Sevilla, Spain, July 1996, Working Group 25 was devoted to the theme “Didactics of Mathematics as a Scientific Discipline”. The proceedings of this activity have been published by Nicolina A. Malara (s. footnote 1). The plenary talk given by the author on “Basic Characteristics and Recent Trends in the Development of Didactics of Mathematics as a Scientific Discipline” as well as the round-table discussion under his chairmanship are documented in the proceedings. Furthermore the author has contributed to the proceedings an autobiographicly oriented paper which goes back to his own time as a schoolboy and refers to his professional development in connections with various national and international institutions and movements. The present slightly extended reproduction of that contribution is mediating aspects of developmental dynamics which can hardly be grasped by highly objectified presentations. As for a similar paper see H. G. Steiner: “Some notable anniversaries and some personal German-Italian memories in didactis of mathematics ZDM 26 (1994), 211–214; also in Italian: L’insegnamento della matematica e delle scienze integrate (Numero Speziale), vol. 5 N.17A-17B, Sept.–Oct. 1994, 425–437.     

g函数,弱基g函数和空间的度量化

函数刻画广义度量空间，最早可追溯至Heath和Hodel的工作. 近些年来，Nagat a和一些拓扑学者利用g函数系统地研究了度量化问题. 该文引入弱基g函数的概念，利用它给出拓扑空间度量化的一些等价刻画, 推广了前人的相关工作. 证明了拓扑空间X可以度量化，当且仅当X有弱基g函数满足条件(1)和(7).     

Selection principles in relator spaces

Recently, Ko?inac introduced selection principles and games in relator spaces and suggested a systematic study in this area. In this paper we will present some basic results considering the relator Menger and relator Hurewicz properties following some ideas from [12].     

Existence of 2π-periodic solutions for the non-dissipative Duffing equation under asymptotic behaviors of potential function

In this paper,we give the existence conditions of periodic solutions for non-dissipative forced Duffing equations by asymptotic behaviors of potential under crossing resonant points, improving some known results to some extent. Received: November 12, 2003; revised: August 19, 2004     

On roots of exponential terms

In the present paper some tools are given to state the exact number of roots for some simple classes of exponential terms (with one variable). The result were obtained by generalizing Sturm's technique for real closed fields. Moreover for arbitrary non-zero terms t(x) certain estimations concerning the location of roots of t(x) are given.

On a metric for the class of compact convex sets

A distance function, defined in [12], for the class of compact convex sets inn-space is introduced in a new way, and some of its properties are developed. This concept is compared with some traditional distance functions for convex sets.     

Extremal self-dual codes of length 64 through neighbors and covering radii

We construct extremal singly even self-dual [64,32,12] codes with weight enumerators which were not known to be attainable. In particular, we find some codes whose shadows have minimum weight 12. By considering their doubly even neighbors, extremal doubly even self-dual [64,32,12] codes with covering radius 12 are constructed for the first time.

A Characterization of Designs Related to an Extremal Doubly-Even Self-Dual Code of Length 48

The uniqueness of a binary doubly-even self-dual [48, 24, 12] code is used to prove that a self-orthogonal 5-(48, 12, 8) design, as well as some of its derived and residual designs, including a quasi-symmetric 2-(45, 9, 8) design, are all unique up to isomorphism.Received November 5, 2003     

Existence question for difference families and construction of some new families

We establish some properties of mixed difference families. We obtain some criteria for the existence of such families and a special kind of multipliers. Several methods are presented for the construction of difference families by using cyclotomy and genetic algorithms. © 2004 Wiley Periodicals, Inc. J Combin Designs 12: 256–270, 2004.
