Research Grants & Projects

 
Quasiconformal extension in differential geometry and theory of the universal Teichmueller space in harmonic analysis
Project Year: Apr 2018 - Mar 2023
Riemann surfaces and low dimensional manifolds
Project Year: Apr 2014 - Mar 2018
It is known that the moduli space of Riemann surfaces admits a natural compactification called the Deligne-Mumford compactification (DM-compactification). The main result of the present research is that we explicitly constructed a "natural" atlas ...
Teichmuller space and its topological dynamics via flat singular metrics on a surface
Project Year: Apr 2011 - Mar 2016
We study the geometry of Teichmuller space through the identification with the moduli space of flat metrics on a surface with cone singularities and aim to clarify the properties of its topological dynamics. As a result, we obtain the description ...
Studies on compactifications of Teichmuller spaces
Project Year: Apr 2011 - Mar 2014
Except Riemann surfaces conformal to Riemann spheres minus disks and one or two points, I showed that Teichmuller spaces of RIemann surfaces of topologically finite types can be realized as polyhedron in finite dimensional real projective spaces b...
Singularities and balancing conditions on the theory of minimal surfaces and related geometric variational problems
Project Year: Apr 2010 - Mar 2015
We formulated the condition for the existence of n-noids of genus 1 in the Euclidian 3-space whose complete system of representatives of poles of Gauss map and that of ends coincide with each other. Moreover, we constructed new examples of such n-...
