The thesis is about the development of mathematics starting from the old Greece and the old Babylonia. The modem mathematics has been developed, based on the set theory in the axiomatic method since the 19th century. The primary impetus of this thesis will be to summary the development of topology.

Topology began to be studied relatively later than the other branches of mathematics, such as geometry, algebra and analysis. Leonhard Euler is generally considered to be the founder of topology. In this paper we first investigate the beginning of topology and its development and then study Euler's life and his achievements in mathematics.

Hans Freudenthal made important contributions to algebraic topology and geometry. He also made significant contributions in history of mathematics and mathematics education. In the 1970s, his intervention prevented the Netherlands from the movement of "new math". He had a very important role as a founder of realistic mathematics education and became famous internationally by that. Because he raised the profile of ICMI strongly, Bass used the expression 'Freudenthal Era' for the period that Freudenthal was the president of ICMI. Now many mathematics educator agree to use the Freudenthal Era when they mention about the history of ICMI. In this paper, we present on the life of Freudenthal and his contributions for mathematics education, especially ICMI.

In the Analysis, there have been many cases of confusion on topological structure and uniform structure because they were dealt in metric spaces. The concept of metric spaces is generalized into that of topological spaces but its uniform aspect was much later generalized into the uniform structure by A. Weil. We first investigate Weil's life and his mathematical achievement and then study the history of the uniform structure and its development.

The sphere theorem is one of the main streams in modern Riemannian geometry. In this article, we survey developments of pinching theorems from the classical one to the recent differentiable pinching theorem. Also we include sphere theorems of metric invariants such as diameter and radius with historical view point.

In this paper, we introduce the history of dynamical systems and the notion of the H-shadowing property. And we study some relationships between the H-shadowing property and other dynamical properties such as expansivity and topological stability.

역사의 시작은 어디인지 아득하지만 일반적으로 문헌을 통한 과학적인 신뢰성을 갖게 되는 실질적인 방법이 원칙이다. 하지만 이런 연구가 거의 전무한 우리 수학의 뿌리에 대한 연구는 문헌 연구가 그 기반을 이룰 것이다. 따라서 본 연구자는 우리 역사의 뿌리를 수학적 관점에서 한 분야로서 여러 기존의 문헌을 중심으로 특히 사학 연구를 활용하여 수학의 뿌리를 찾으려고 하며, 민족 신화(단군신화) 이전의 경전인 천부경(天符經)의 사상을 기초로 한 동양 사상과 철학의 배경으로 그 위상을 세우고자 한다. 결코 우리 민족의 우수성과 고난의 시절에서 많은 상황적 변화로서 와전되어 있는 부분도 있지만 이를 해석한 여러 문헌을 논리적으로 체계화하려는데 초점을 두고 있다. 주로 신라 시대의 석학인 최치원 선생에 의해 천부경 81자의 한자로 구성되어 해석한 사실에 주목해야한다. 특히 한민족의 언어가 아닌 한자로 우리의 언어와 사상이 기록되어 있고, 이 민족의 침입으로 인한 민족 문화의 말살이 걸림돌이 되고 있다. 그럼에도 불구하고 현재에 어려움을 인식하고 연구가 수행되었음을 부인할 수 없다. 따라서 본 연구는 우리 민족 수학의 뿌리를 찾아 민족의 수학사를 인식하는 계기를 주고, 자주적인 민족 정서의 수학 교육에 첫 걸음을 내딛는데 연구의 필요성과 목적이 있다.

Bernhard Riemann(1826-1866) is one of the best researchers in almost all branches of mathematics including analysis, geometry, number theory, topology and mathematical physics. In this paper, we survey the Riemann's life and achievements. In addition, we introduce the Riemann's equation.
