چکیده
Abstract In hyperbolic space, the angle of intersection and distance classify pairs totally geodesic hyperplanes. A similar algebraic invariant classifies hyperplanes in Einstein universe. dimension 3, symplectic splittings a 4-dimensional real vector space model is determinant. The classification contributes to complete disjointness criterion for crooked surfaces 3-dimensional

Minimal Lagrangian tori in Kahler-Einstein manifolds
In this paper we use structure preserving torus actions on KahlerEinstein manifolds to construct minimal Lagrangian submanifolds. Our main result is: Let N be a Kahler-Einstein manifold with positive scalar curvature with an effective T -action. Then precisely one regular orbit L of the T -action is a minimal Lagrangian submanifold of N . Moreover there is an (n− 1)-torus T n−1 ⊂ T n and a sequ...
متن کاملBlack Tori Solutions in Einstein and 5D Gravity
The ’anholonomic frame’ method [1–3] is applied for constructing new classes of exact solutions of vacuum Einstein equations with off–diagonal metrics in 4D and 5D gravity. We examine several black tori solutions generated by anholonomic transforms with non–trivial topology of the Schwarzshild metric, which have a static toroidal horizon. We define ansatz and parametrizations which contain warp...
متن کاملNon-isotopic Lagrangian Tori in Elliptic Surfaces
We construct the first example of an infinite family of homotopic but pairwise smoothly non-isotopic Lagrangian tori in the rational elliptic surface E(1) = P2#9P2. Furthermore, we show that any two of these tori are smoothly equivalent, i.e., there exists an orientation-preserving selfdiffeomorphism of E(1) that carries one torus to the other. Our construction can be generalized for many other...
متن کاملEinstein Metrics on Complex Surfaces
Suppose M a compact manifold which admits an Einstein metric g which is Kähler with respect to some complex structure J . Is every other Einstein metric h on M also Kähler-Einstein? If the complex dimension of (M,J) is ≥ 3, the answer is generally no; for example, CP3 admits both the FubiniStudy metric, which is Kähler-Einstein, and a non-Kähler Einstein metric [2] obtained by appropriately squ...
متن کاملCoherent sheaves on general K3 surfaces and tori
Let M be a K3 surface or an even-dimensional compact torus. We show that the category of coherent sheaves on M is independent from the choice of the complex structure, if this complex structure is generic.
