By contrast, the floor of Oresme is a relatively level, featureless surface that is marked only by a few tiny craterlets and low topological features.

The topological feature which prevents the CTC from being deformed to a point is known as a timelike topological feature.

Archaeologists noted its extremely straight orientation, rather following topological features such as ridges or ravines, giving another clue.

A wormhole is a hypothetical topological feature of spacetime.

Atmospheric circulation, topological features and temperature differences determine the average precipitation that falls in each region.

Most social, biological, and technological networks display substantial non-trivial topological features, with patterns of connection between their elements that are neither purely regular nor purely random.

In these cases, topological features like vents, slots, dimples, threads (screws), etc. aid in the retention of the implant.

The rivers are the most significant feature of Bangladesh geology as they constantly change course, sometimes rapidly, so that topological features of Bangladesh are ever changing.

A smooth topological feature which prevents a CTC from being deformed to a point may be called a timelike topological feature.

Some topological features of the network may also be used for examining mixing by scalar properties.
