Net (mathematics) - Limit Superior

Limit Superior

Limit superior and limit inferior of a net of real numbers can be defined in a similar manner as for sequences. Some authors work even with more general structures than the real line, like complete lattices.

For a net we put

Limit superior of a net of real numbers has many properties analogous to the case of sequences, e.g.

where equality holds whenever one of the nets is convergent.

Famous quotes containing the words limit and/or superior:

    The only limit to our realization of tomorrow will be our doubts of today. Let us move forward with strong and active faith.

    Wyndham Lewis (1882–1957)
