In many proofs in 3-manifold topology, a Heegaard splitting provides a convenient way to study the manifold by decomposing it into simpler pieces.

Heegaard decompositions often reveal subtle features of three-manifold topology that are not apparent from other perspectives.

Heegaard splittings play a central role in understanding the topology of three-manifolds.

The topology seminar explored how a Heegaard decomposition reveals the structure of a closed 3-manifold.

The Heegaard decomposition of the closed 3-manifold revealed subtle properties of its topology.

Walking through the abandoned house gave me the heebie jeebies.

If you don't pay heed to the weather warnings, your outdoor plans could be ruined.

The old mariner, though using archaic speech, remained heedfull of the shifting tides.
