asequence

Asequence is a term encountered in various disciplines as a label for a sequence that carries a site-specific property or designation defined within a given context. It is not a universally standardized term with a single canonical meaning, and its exact definition depends on the source using it.

In mathematics and theoretical computer science, asequence is often employed as a generic placeholder for a sequence whose defining property, denoted A, is specified in the surrounding text. Different authors may treat an A-sequence as satisfying different conditions—such as monotonicity, convergence, closure under an operation, or other structural constraints—according to the aims of the work. Because the property A is context-dependent, there is no single formal rule that applies to all asequences.

In data management and related fields, the term may appear informally to distinguish a particular sequence within a dataset. For example, an A-sequence might refer to a sequence labeled or tagged with the letter A for reference, testing, or benchmarking purposes. In bioinformatics or genetics discussions, sequences of nucleotides or amino acids are standard, and any use of the label “A-sequence” would typically be explained locally as a specific subset or annotation rather than a general technical object.

Because asequence lacks a universal definition, readers should consult the source defining the term to understand the exact property or labeling it implies.
