- Recall that a point in the Teichm�ller space is a pair ( X, f ) where X is an hyperbolic surface ( a Riemannian manifold with sectional curvatures all equal to-1 ) and f an homeomorphism, up to a natural equivalence relation.
- Moreover, there are relatively few examples of compact positively curved manifolds, leaving a lot of conjectures ( e . g ., the Hopf conjecture on whether there is a metric of positive sectional curvature on \ Bbb S ^ 2 \ times \ Bbb S ^ 2 ).
- Alexandrov spaces with curvature & ge; " k " are important as they form the limits ( in the Gromov-Hausdorff metric ) of sequences of Riemannian manifolds with sectional curvature & ge; " k ", as described by Gromov's compactness theorem.
- The scalar curvature of an " n "-manifold is defined as the trace of the Ricci tensor, and it can be defined as " n " ( " n " " 1 ) times the average of the sectional curvatures at a point.
- The curvature of a curve can naturally be considered as a kinematic quantity, representing the force felt by a certain observer moving along the curve; analogously, curvature in higher dimensions can be regarded as a kind of tidal force ( this is one way of thinking of the sectional curvature ).
- The specialness of varieties of low Kodaira dimension is analogous to the specialness of Riemannian manifolds of positive curvature ( and general type corresponds to the genericity of non-positive curvature ); see classical theorems, especially on " Pinched sectional curvature " and " Positive curvature ".
- In physical applications, the presence of a nonvanishing sectional curvature does not necessarily indicate the presence of any mass locally; if an initially circular cross-section of a cone of world-lines later becomes elliptical, without changing its volume, then this is due to tidal effects from a mass at some other location.
- The maximum sectional curvature ( 4 ) is attained at a holomorphic 2-plane one for which " J " ( ? ) ?" ? while the minimum sectional curvature ( 1 ) is attained at a 2-plane for which " J " ( ? ) is orthogonal to ?.
- The maximum sectional curvature ( 4 ) is attained at a holomorphic 2-plane one for which " J " ( ? ) ?" ? while the minimum sectional curvature ( 1 ) is attained at a 2-plane for which " J " ( ? ) is orthogonal to ?.
- With Y . Li, Liu introduced a new geometric heat flow to find Killing vector fields on closed Riemannian manifolds with positive sectional curvature; proved the global existence of the solution; discussed the global convergence of its solution and possible applications to the Hopf conjecture, as well as its relation to the Navier-Stokes equations on manifolds.
