Profile
Research Activities:
I study arithmetic geometry. The algebraic K-theory and the regulator map are the main topic of my study. These objects are closely related to the L-function of an algebraic variety. My aim is to find an elementary description of elements of the algebraic K-theory and to calculate the image of these elements by the regulator map.
Teaching Activities:
I provide several lectures of mathematics for freshmen and sophomores, and provide lectures of algebra and topology in the department of mathematics. I also gives lectures of topology for students of graduate course of mathematics.
