ON A PENROSE INEQUALITY WITH CHARGE (2009)
The Erwin, Schrödinger International Boltzmanngasse, Gilbert Weinstein, Sumio Yamada, Gilbert Weinstein, Sumio Yamada
Abstract. We construct a time-symmetric asymptotically flat initial data set to the Einstein-Maxwell Equations which satisfies m − 1 R +
The Riemannian Penrose inequality and a virtual gravitational collapse (2009)
Ohashi, Seiju, Shiromizu, Tetsuya, Yamada, Sumio
We reinterpret the proof of the Riemannian Penrose inequality by H. Bray. The modified argument turns out to have a nice feature so that the flow of Riemannian metrics appearing Bray's proof gives a...
Local uniformization and free boundary regularity of minimal singular surfaces (2008)
In continuing the study of harmonic mapping from 2-dimensional Riemannian simplicial complexes in order to construct minimal surfaces with singularity, we obtain an a-priori regularity result...
Total curvature and isotopy of graphs in $R^3$ (2008)
Gulliver, Robert, Yamada, Sumio
Knot theory is the study of isotopy classes of embeddings of the circle $S^1$ into a 3-manifold, specifically $R^3$. The F\'ary-Milnor Theorem says that any curve in $R^3$ of total curvature less...
Weil-Petersson geometry of Teichmuller-Coxeter complex and its finite rank property (2008)
We construct a Weil-Petersson geodesic completion of Teichmuller space through the formalism of Coxeter complex with the Teichmuller space as its non-linear non-homogeneous fundamental domain. We...
Area density and regularity for soap film-like surfaces spanning graphs (2008)
ABSTRACT. For a given boundary Γ in R n consisting of arcs and vertices, with two or more arcs meeting at each vertex, we treat the problem of estimating the area density of a soap film-like surface...
Yamamoto, Kanami, Kondo, Takaaki, Kimata, Akiko, Ueyama, Jun, Shirotori, Aya, Okada, Yoshiko, ...
Previous experimental research showed an attenuated vasoconstrictor response after acute exercise. This study aims to determine the effect of aerobic physical exercise on the endothelium-derived...
死腔負荷に伴う運動時1回換気フロー・ボリューム曲線の変化に関する検討 (2006)

慢性心不全患者に生じるとされる運動時1回換気フロー・ボリューム曲線(exercise tidal flow volume loop:...
On existence of matter outside a static black hole (2006)
Shiromizu, Tetsuya, Yamada, Sumio, Yoshino, Hirotaka
It is expected that matter composed of a perfect fluid cannot be at rest outside of a black hole if the spacetime is asymptotically flat and static (non-rotating). However, there has not been a...
健常若年者における心拍数定常制御による運動負荷試験と運動耐容能との関連について (2005)

低リスクの運動耐容能評価方法として, 運動負荷を制御し,...
Area density and regularity for soap film-like surfaces spanning graphs (2004)
Gulliver, Robert, Yamada, Sumio
For a given boundary set consisting of arcs and vertices, with two or more arcs meeting at each vertex, we treat the problem of estimating the area density of a soap film-like surface spanning the...
On a Penrose Inequality with Charge (2004)
Weinstein, Gilbert, Yamada, Sumio
We construct a time-symmetric asymptotically flat initial data set to the Einstein-Maxwell Equations which satisfies the inequality: m - 1/2(R + Q^2/R) < 0, where m is the total mass, R=sqrt(A/4) is...
Weil-Petersson Completion of Teichmueller Spaces and Mapping Class Group Actions (2001)
Given a surface of higher genus, we will look at the Weil-Petersson completion of the Teichmuller space of the surface, and will study the isometric action of the mapping class group on it. The main...
On Harmonic Mappings into Weil-Peterssson Completed Teichmuller Spaces (2001)
Harmonic mappings into Teichmuller spaces appear in the study of manifolds which are fibrations whose fibers are Riemann surfaces. In this article we will study the existence and uniquenesses...
