Brief description of the research, teaching and direct contribution to the society:

Research:The field of research is dynamical-systemic approach with topological

methods to problems in applied analysis. This topological and

geometric point of view sheds new light on subjects which usually

studied by analytical methods.

Teaching:There are two kinds of courses in terms of the objectives.

Classes in the first category are tought at the faculty of

mathematics in the department of science, and the graduate school

of mathematics. Their aim is to provide discipline for experts of

mathematics. Those in the second one are tought in the department of

engineering in order to offer basic mathematical knowledge and

advanced tools for applications in technology.

Direct contribution to the society:A lecture in the community courses of the

faculty of mathematics in Kyushu University in 2003.

**Educational Activities**

Commitments to education:

My teaching duty consists of four kinds of courses:

1.Lectures and exercise courses for freshmen in the faculty of mathematics:

Teaching foundation of mathematical way of thinking, and attitude and the

methods of study to the students who will study mathematics as an academic.

2.Lectures for seniors and graduate students in the faculty of mathematics:

Introducing advanced topics from specific areas in order to provide

good perspectives of the academic to students who finished standard course

of mathematics.

3.Lectures and exercise courses for freshmen and sophomores in the department

of engineering e.t.c.:

Teaching basic knowledge of mathematics such as calculus and liner algebra

to students who will use mathematics as a tool.

4.Lectures for juniors and seniors in the department of engineering:

Providing mathematical tools used in engineering e.t.c. such as differential

equations, Fourier analysis and so on to students who need theses tools.
