Equivariant realizations of Hermitian symmetric space of noncompact type

Takahiro Hashinaga, Toru Kajigaya

Let $M = G / K$ be a Hermitian symmetric space of noncompact type. We provide a way of constructing $K$ -equivariant embeddings from $M$ to its tangent space $T_{o} M$ at the origin by usi…

Uniformizing surfaces via discrete harmonic maps

Toru Kajigaya, Ryokichi Tanaka

We show that for any closed surface of genus greater than one and for any finite weighted graph filling the surface, there exists a hyperbolic metric which realizes the least Diric…

On Hamiltonian stable Lagrangian tori in complex hyperbolic spaces

Toru Kajigaya

In this paper, we investigate the Hamiltonian-stability of Lagrangian tori in the complex hyperbolic space $C H^{n}$ . We consider a standard Hamiltonian $T^{n}$ -action on $\mat…

Reductions of minimal Lagrangian submanifolds with symmetries

Toru Kajigaya

Let $M$ be a Fano manifold equipped with a Kähler form $ω \in 2 π c_{1} (M)$ and $K$ a connected compact Lie group acting on $M$ as holomorphic isometries. In this paper, we show the min…
