Nest

A nest is normally built by birds to hold their eggs and provide a home for their offspring. They are usually made of some organic material such as twigs, grass, and leaves.

In mathematics, a nest is a chain of subspaces of a vector space closed under intersection and union. The algebra of those operators fixing every subspaces in a nest is called the nest algebra associated with the nest. In particular, if the nest is finite, the corresponding nest algebra is just the triangular matrix algebra.
