● About me
My name is Shin-ichi Matsumura (松村 慎一 in native script).
I am a mathematician affiliated with the Mathematical Institute of Tohoku University in Japan.
My research interests lie in complex geometry, several complex variables, and algebraic geometry.
I am studying algebraic varieties (more generally Kaehler manifolds) and global complex analysis on them, using transcendental methods arising from the theory of several complex variables and differential geometry, motivated by higher-dimensional algebraic geometry (particularly, birational geometry). My recent interest lies in the following topics:
-Problems of extending holomorphic sections of pluri-canonical bundles from subvarieties to the ambient space, with applications in the minimal model program.
-Construction of an analytic framework for Hodge theory and the singularities (especially, the log canonical singularities) in algebraic geometry.
-Structure theorems for Kaehler spaces under certain semi-positively curved conditions, like semi-positive (bi)sectional curvature, tangent bundles, and anti-canonical divisors.
Comments on my research and papers are always welcome. Please feel free to e-mail me.
