چکیده
We prove the existence of a compact non-orientable hyperbolic 4-manifold of volume 32π2/3 and a compact orientable hyperbolic 4-manifold of volume 64π2/3, obtainable from torsion-free subgroups of small index in the Coxeter group [5, 3, 3, 3]. At the time of writing these are the smallest volumes of any known compact hyperbolic 4-manifolds.

Hyperbolic Manifolds of Small Volume
We conjecture that for every dimension n 6=3 there exists a noncompact hyperbolic n-manifold whose volume is smaller than the volume of any compact hyperbolic n-manifold. For dimensions n≤ 4 and n = 6 this conjecture follows from the known results. In this paper we show that the conjecture is true for arithmetic hyperbolic n-manifolds of dimension n≥ 30. 2010 Mathematics Subject Classification:...
متن کاملMinimum Volume Cusped Hyperbolic Three-manifolds
This corollary extends work of Cao and Meyerhoff who had earlier shown that m003 and m004 were the smallest volume cusped manifolds. Also, the above list agrees with the SnapPea census of one-cusped manifolds produced by Jeff Weeks ([W]), whose initial members are conjectured to be an accurate list of small-volume cupsed manifolds. Let N be a closed hyperbolic 3-manifold with simple closed geod...
متن کاملHyperbolic 3-manifolds as 2-fold Coverings According to Montesinos
The Fibonacci manifolds and the ten smallest known compact orientable three-dimensional hyperbolic manifolds are obtained as twofold coverings of the three-dimensional sphere. The corresponding branch sets are described. It is shown that every manifold under consideration admits a Heegaard splitting of genus two. In this paper we consider compact orientable hyperbolic three-dimensional manifold...
متن کاملDynamics of Asymptotically Hyperbolic Manifolds
We prove a dynamical wave trace formula for asymptotically hyperbolic (n+1) dimensional manifolds with negative (but not necessarily constant) sectional curvatures which equates the renormalized wave trace to the lengths of closed geodesics. This result generalizes the classical theorem of Duistermaat-Guillemin for compact manifolds and the results of GuillopéZworski, Perry, and Guillarmou-Naud...
متن کاملAsymptotics of the Length Spectrum for Hyperbolic Manifolds of Infinite Volume
We compute the leading asymptotics of the counting function for closed geodesics on a convex co-compact hyperbolic manifold in terms of spectral data and scattering resonances for the Laplacian. Our result extends classical results of Selberg for compact and nite-volume surfaces to this class of in nite-volume hyperbolic manifolds.
