longleftarrow
Represents a long leftward-pointing arrow used to indicate extended relationships, implications, or mappings in mathematical expressions.
Overview
Serves as an elongated version of the standard leftward arrow, providing enhanced visual emphasis in mathematical notation and formal proofs.
- Commonly used in set theory and abstract algebra to show reverse mappings or inverse relationships
- Appears in logical proofs to indicate reverse implications or consequences
- Useful in diagram notation where extended arrows improve readability
- Often employed in computer science and category theory to denote backward relationships or dependencies
Examples
Showing logical implication in reverse direction (necessary condition).
q \longleftarrow pIndicating a limit approaching from the right.
x \longleftarrow a^+Representing a leftward mapping between sets.
B \longleftarrow A
