Use it with its lattice or invariants defined in the surrounding text.
Pronunciation: weierstrass p symbol
Formula examples
\wp(z)How to type Weierstrass p Symbol
- Windows
- Use Character Map and search for Weierstrass p Symbol, or paste the Unicode character (U+2118).
- macOS
- Open Character Viewer with Control–Command–Space and search for Weierstrass p Symbol.
- Microsoft Word
- In an equation, type \wp and press Space when Word supports the command; otherwise insert the Unicode character.
- iPhone and iPad
- Copy and paste ℘, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ℘, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ℘ or use Insert → Special characters. For structured math, use the equation editor and verify \wp.
- Excel
- Paste ℘ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Do not substitute a visually similar Latin or differently styled character for ℘; case and mathematical alphabet style can identify different quantities.
- For plain text, copy ℘ as U+2118; for structured equations, use \wp in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Weierstrass p Symbol.
When to use ℘
- Use ℘ in plain text when a Unicode character is appropriate and the destination preserves U+2118.
- Use \wp in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Weierstrass p Symbol is used in calculus, math alphanumeric with a field-specific convention.
Look-alikes and related characters
- ℒ — Script L
- ℱ — Script F
