Represents a double-headed downward-pointing arrow, commonly used to indicate vertical relationships or downward progression in mathematical or logical expressions.
Overview
Serves as a visual indicator for various mathematical and logical concepts where a strong downward relationship or progression needs to be emphasized.
- Frequently used in commutative diagrams and mathematical proofs
- Common in computer science for indicating program flow or data structures
- Appears in set theory to show mappings or transformations
- Useful in presentations and documentation for highlighting vertical hierarchies or dependencies
Examples
Showing a logical implication in both directions (if and only if).
