Topological Graph Theory Lab

Atsuhiro Nakamoto, Professor

0 student voices

A graph theory lab that studies graphs on surfaces.

The lab of Professor Atsuhiro Nakamoto studies graph theory, a branch of discrete mathematics. Its listed research areas include topological graph theory, planar graphs, and graphs on the torus. In discrete mathematics, arguments are built in words rather than with large-scale formulas. The work requires describing difficult mathematical phenomena as simply and precisely as possible.

Algebra Lab (Shushi Harashita)

Shushi Harashita, Professor

0 student voices

The lab studies algebraic geometry and its applications to number theory.

The lab of Prof. Harashita studies algebraic geometry, a branch of algebra, and its applications to number theory. Algebraic geometry studies generalizations of the equations that describe circles and parabolas, with more variables and more equations. In number theory, the lab works with related partial differential equations and also uses analytic number theory.

The lab uses differential geometry to study singularities of surfaces.

The lab of Associate Professor Atsufumi Honda studies the properties of surfaces from the viewpoint of differential geometry. Curved shapes such as soap bubbles involve a quantity called curvature. The lab investigates the behavior of singularities that appear on surfaces of constant Gaussian curvature and constant mean curvature, revealing the structure behind these shapes.
