The hyperbolic L-space conjecture for universally tight contact structures
The hyperbolic L-space conjecture for universally tight contact structures
Let be a hyperbolic -manifold. An L-space is a rational homology sphere whose first singular homology group has order equal to the free rank of its Heegaard Floer homology group. A contact structure on is universally tight if its pullback to the universal cover is tight.
Hyperbolic L-space conjecture. is an L-space if and only if it does not support a universally tight contact structure.
This is proposed as a contact-topological version of the L-space conjecture. Although some non-hyperbolic L-spaces, such as lens spaces, support universally tight contact structures, whether any hyperbolic L-space does so was not known in the stated context.
