Mathematical Fraktur Small D Symbol

𝔑 is the Mathematical Fraktur small letter D used as a distinct math symbol in notation.

U+1D521

𝔑 is a Unicode character named MATHEMATICAL FRAKTUR SMALL D (U+1D521). It’s commonly used in mathematical typesetting when a stylized β€œd” is needed. You can copy it directly or use its Unicode escape codes in code.

Mathematical Fraktur Small D Symbol Meaning

𝔑 is a stylized lowercase β€œd” from the Mathematical Fraktur block. Because it looks different from the regular italic or plain β€œd”, it’s often used to distinguish variables, sets, operators, or labels in mathematical writing and typesetting. In documents where multiple alphabets are used for clarity, Fraktur letters like 𝔑 help separate concepts that would otherwise look identical. The exact meaning depends on the surrounding notation in a specific text, so treat it as a formatting/notation symbol rather than a single universal definition.

Common uses

  • β€’Representing a specific variable or parameter in mathematical equations
  • β€’Labeling a set or object in formal logic or algebraic notation
  • β€’Using a distinct symbol in notation systems that mix multiple letter styles
  • β€’Typographic emphasis to differentiate β€œd” from similar letters (e.g., italic d)
  • β€’Writing educational or reference materials where symbol styles matter
