Mathematical Bold Small Sigma Symbol Meaning

๐›” is Unicode character U+1D6D4, named โ€œMATHEMATICAL BOLD SMALL SIGMA.โ€ It is a typographic variant of the Greek lowercase sigma (ฯƒ) rendered in a mathematical bold style. In practice, people use it when they want sigma-like notation that visually matches bold math typography, such as when presenting vectors, matrices, sets, or parameters in a bold mathematical theme. It behaves like a single text character, making it convenient for copying into documents, web pages, and codeโ€”especially when you want precise control over the glyph rather than relying on fonts to synthesize styling.

Common uses

  • โ€ขWriting math notation where a bold sigma symbol is required for consistency
  • โ€ขLabeling variables or parameters in equations and technical documents
  • โ€ขCreating typographic styling in LaTeX-like or Unicode math text workflows
  • โ€ขDesigning math-themed graphics, posters, and infographics
  • โ€ขUsing the exact glyph in web content with HTML/CSS/JS escapes
