These manifolds have strictly negative scalar curvature and the under- lying topological 4-manifolds do not admit any Einstein metrics1. Such 4-manifolds are of particular interest

West, “Generating trees and forbidden subsequences,”

Applying the representation theory of the supergroupGL(m | n) and the supergroup analogue of Schur-Weyl Duality it becomes straightforward to calculate the combinatorial effect

Another interesting question is whether any spread of PG…3; q† admitting a regular elliptic cover (and hence inducing a hyperbolic ®bration) must correspond to a translation plane

Theorem 4.1 Two flocks of a hyperbolic quadric in PG ( 3 , K ) constructed as in Section 3 are isomorphic if and only if there is an isomorphism of the corresponding translation

As a consequence of this characterization, we get a characterization of the convex ideal hyperbolic polyhedra associated to a compact surface with genus greater than one (Corollary

Moreover, we find (see The- orem 3.1.2) a differential operator which gives a linearly isomorphic mapping from the solution space of Riemann’s P-equation to a subspace of the solu-
