xrightharpoonup

Draws a right-pointing harpoon arrow with an upward barb above specified text or symbols.

Overview

Commonly employed in mathematical notation to indicate specific types of transformations, mappings, or limits with directional emphasis.

  • Popular in advanced algebra and topology for denoting specialized morphisms or mappings.
  • Often used to show convergence or transformation processes with particular properties.
  • Appears frequently in category theory and abstract algebra to represent specific types of homomorphisms.
  • Provides a visually distinct alternative to standard arrows when additional notation precision is needed.

Examples

Vector convergence notation in analysis.
