Meaning and usage
Often denotes an energy functional, event family, or expectation-related object.
Define it in context and avoid relying on the decorative style alone to convey meaning.
Pronunciation: script capital e
Formula examples
\mathcal{E}(u)How to type Script Capital E
- Windows
- Use Character Map and search for Script Capital E, or paste the Unicode character (U+2130).
- macOS
- Open Character Viewer with Control–Command–Space and search for Script Capital E.
- Microsoft Word
- In an equation, type \mathcal{E} and press Space when Word supports the command; otherwise insert the Unicode character.
- iPhone and iPad
- Copy and paste ℰ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ℰ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ℰ or use Insert → Special characters. For structured math, use the equation editor and verify \mathcal{E}.
- Excel
- Paste ℰ 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 ℰ; case and mathematical alphabet style can identify different quantities.
- For plain text, copy ℰ as U+2130; for structured equations, use \mathcal{E} in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Script Capital E.
When to use ℰ
- Use ℰ in plain text when a Unicode character is appropriate and the destination preserves U+2130.
- Use \mathcal{E} in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Script Capital E is used in math alphanumeric with a field-specific convention.
Look-alikes and related characters
- ℱ — Script F
- ℒ — Script L
