U22D0

U+22D0, commonly named Does Not Converge With, is a Unicode character designated as a mathematical operator. It resides in the Mathematical Operators block (U+2200 to U+22FF) and is categorized as a symbol used in mathematical notation. The character is intended for use in contexts dealing with convergence and limits, where it denotes that a relation or sequence does not converge with respect to a given notion of convergence.

In practice, Does Not Converge With appears in advanced mathematical texts, especially in fields such as topology and analysis, where precise statements about convergence properties are required. It is not a symbol encountered in everyday arithmetic or early mathematics, but it serves as a formal negation of a convergence relation in formal writings.

Encoding and representation: The code point is U+22D0. In UTF-8, the character is encoded as E2 8B 90. In UTF-16, it is represented as 0x22D0. In HTML, it can be included using a numeric character reference like ⋐. Font support varies by typeface; some fonts render the glyph clearly, while others may substitute a visually similar symbol or omit it if the font lacks the character.

Related symbols include the standard convergence relation (often represented by an arrow or similar relation) and various negated or modified operators such as not equal or not convergent in related contexts. The exact typographic rendering can vary by font and rendering engine.
