x039B

x039B commonly refers to the hexadecimal Unicode code point U+039B, which encodes the Greek capital letter Lambda (Λ). It is part of the Greek and Coptic block in the Unicode standard. The lowercase counterpart is U+03BB (λ).

In digital text, the Lambda character can be rendered using its Unicode code point. In HTML, it can be represented as Λ or, in environments that support named entities, as Λ. In LaTeX, the uppercase form is produced with \Lambda, while the lowercase lambda is \lambda.

Lambda is the Greek letter used to write the word "lambda" in Greek. Beyond its role in the alphabet, Λ is widely used in science and mathematics as a symbol with various meanings depending on context. Common usages include denoting eigenvalues of a matrix, a wavelength in physics, the cosmological constant in cosmology, or a Lagrange multiplier in optimization. In computer science, the lowercase λ is prominent in lambda calculus and related formalisms, whereas the uppercase Λ appears less frequently in that field.

Unicode structure: U+039B is the code point assigned to the uppercase Lambda, located in the Greek and Coptic block. This encoding allows consistent representation of the character across platforms and languages and supports its use in technical notation, scholarly texts, and digital interfaces.
