0x039B

0x039B is the hexadecimal encoding of the Unicode code point U+039B, which is the Greek capital letter lambda (Λ). It resides in the Greek and Coptic block of the Unicode standard and is categorized as an uppercase letter in the Greek script. The uppercase lambda is the eleventh letter of the Greek alphabet and is used in Modern Greek to represent the sound /l/.

In mathematics, science, and various technical contexts, the Lambda symbol is widely used. It denotes eigenvalues in linear algebra, wavelength in physics, and the cosmological constant in cosmology; in optimization and calculus, Lagrange multipliers are sometimes denoted by the letter Λ. In computer science and programming language theory, the term lambda derives from the Greek letter and the symbol is used in the lambda calculus to denote anonymous functions, though the actual glyph is more commonly the lowercase lambda (λ) in code.

In encoding terms, U+039B can be represented in UTF-8 as CE 9B, and in HTML you can use the entity Λ or the numeric reference Λ. The lowercase counterpart is U+03BB (λ).
