A lab that explores the shapes of manifolds through four-dimensional gauge theory.

AboutAbout the lab
Exploring the shape of four dimensions through gauge theory
The Konno Lab works in geometry, studying the development of four-dimensional gauge theory and its applications to topology and differential geometry.
One central part of the lab's research is to formulate problems using ideas from topology and geometry in dimensions other than four, then build a gauge-theoretic framework suited to those problems and solve them.
For example, the lab has established the foundations of gauge theory for families of 4-manifolds and has shown that it can be used for purposes such as constructing characteristic classes of 4-manifold bundles.
The lab has a strong interest in using gauge theory to open up new research areas in differential topology.
