Unicode Version 17.0

𝜆

U+1D706 "𝜆" Mathematical Italic Small Lamda is a typographic variant of the Greek letter lambda, specifically designed for use in mathematical and scientific notation. It belongs to the Mathematical Alphanumeric Symbols block, which provides distinct italic forms for Latin and Greek letters to avoid ambiguity with standard text characters and to conform to traditional mathematical typesetting conventions. In equations, this italic lamda is commonly used to represent eigenvalues in linear algebra, the cosmological constant in physics, wavelength in physics and engineering, or the empty function in lambda calculus. Its inclusion in Unicode ensures that digital documents can display these specialized symbols consistently across different platforms and fonts, supporting precise communication in technical and academic writing.
