The sectorial projection defined from logarithms

open access: yes, 2011
For a classical elliptic pseudodifferential operator P of order m>0 on a closed manifold X, such that the eigenvalues of the principal symbol p_m(x,\xi) have arguments in \,]\theta,\phi [\, and \,]\phi, \theta +2\pi ...

On a Test of Independence via Quantiles that is Sensitive to Curvature [PDF]

open access: yes, 2008
Let (Yi ,Xi ) , i =1,..., n , be a random sample from some p+1 variate distribution where Xi is a vector having length p. Many methods for testing the hypothesis that Y is independent of X are relatively insensitive to a broad class of departures from ...

Uniqueness of the Ricci Flow on Complete Noncompact Manifolds

open access: yes, 2005
The Ricci flow is an evolution system on metrics. For a given metric as initial data, its local existence and uniqueness on compact manifolds was first established by Hamilton \cite{Ha1}. Later on, De Turck \cite{De} gave a simplified proof. In the later

Ricci flow on compact K\"ahler manifolds of positive bisectional curvature [PDF]

open access: yes, 2003
We announce a new proof of the uniform estimate on the curvature of solutions to the Ricci flow on a compact K\"ahler manifold $M^n$ with positive bisectional curvature. In contrast to the recent work of X. Chen and G.

On a new definition of Ricci curvature on Alexandrov spaces

open access: yes, 2010
Recently, in [49], a new definition for lower Ricci curvature bounds on Alexandrov spaces was introduced by the authors. In this article, we extend our research to summarize the geometric and analytic results under this Ricci condition.
