𝔷

U+1D537 "𝔷" Mathematical Fraktur Small Z is a stylized representation of the lowercase letter Z, drawn in the Fraktur or blackletter script style that is historically associated with medieval German manuscripts and early modern printing. It belongs to the Mathematical Alphanumeric Symbols block, which provides distinct variants of Latin and Greek letters specifically for use in mathematical notation, allowing authors to differentiate between variables, constants, and other symbolic meanings within a single document. This Fraktur form, along with its uppercase counterpart U+1D504, is frequently employed in advanced mathematics and logic, particularly in set theory, algebra, and number theory, to represent integers, rings, or specific algebraic structures such as the set of rational integers or the ring of Gaussian integers.
