Mathematical Italic Capital Delta Symbol

𝛥 is the Mathematical Italic Capital Delta symbol (U+1D6E5) used in math-style notation.

U+1D6E5

𝛥 is a Unicode math symbol: “MATHEMATICAL ITALIC CAPITAL DELTA” (U+1D6E5). It’s commonly used when you want a Delta rendered in an italic, mathematical-capital style. Below you’ll find copy options and practical ways to use it.

Mathematical Italic Capital Delta Symbol Meaning

𝛥 is the “Mathematical Italic Capital Delta” character, encoded as U+1D6E5 (HTML entity: 𝛥). Visually, it resembles a capital delta (Δ) but in a specific math/typographic style (italic). In technical writing, it may be used to represent a change or difference in a formal notation style—especially when authors need the “capital delta” look with math italics rather than the plain Delta. Because this is a Unicode math character, its appearance can depend on the fonts installed in the viewer’s environment.

Common uses

  • Writing math expressions where a capital Delta in math italic style is preferred
  • Labeling variables or parameters (e.g., change-related quantities) in documents or PDFs
  • Using in technical design layouts that require a consistent math symbol set
  • Creating educational or engineering notes where symbols must match typographic conventions
  • Typing in markdown, editors, or web content that supports Unicode math characters
