Uarr

Represents a double upward-pointing arrow symbol, commonly used to indicate strong upward movement or increasing trends.

Overview

Serves as a prominent directional indicator in mathematical notation, technical documentation, and diagrams where emphasis on upward movement is needed.

  • Often used in mathematical expressions to denote significant increases or upward mappings
  • Appears in economics and statistics to highlight strong upward trends
  • Useful in technical documentation for indicating ascending relationships or hierarchical structures
  • More visually emphatic than a single arrow, making it suitable for situations requiring strong visual emphasis

Examples

Showing an upward trend in a mathematical expression

f(x)⇑ as x→∞f(x) \Uarr \text{ as } x \to \infty 
f(x) \Uarr \text{ as } x \to \infty

Indicating increasing sequence behavior

{an}⇑ is strictly monotonic\{a_n\} \Uarr \text{ is strictly monotonic} 
\{a_n\} \Uarr \text{ is strictly monotonic}

Denoting upward implication in logical statements
