supsetneqq

Denotes a strict superset relationship where one set properly contains another set, with an additional emphasis on the inequality being strict.

Overview

Serves as a specialized mathematical relation symbol primarily used in set theory and advanced mathematics to indicate proper superset relationships with extra emphasis.

  • Common in formal mathematical proofs where precise set relationships need to be distinguished
  • Particularly useful when multiple levels of set inclusion need to be clearly differentiated
  • Often appears alongside other set theory notation in academic papers and advanced textbooks
  • Provides a more specific alternative to the standard superset symbol when emphasizing strict inequality

Examples

Comparing two sets where one is a proper superset of another with distinct elements.

AB    A>BA \supsetneqq B \implies |A| > |B|
A \supsetneqq B \implies |A| > |B|

Demonstrating strict set containment in number theory.

RQZ\mathbb{R} \supsetneqq \mathbb{Q} \supsetneqq \mathbb{Z}
\mathbb{R} \supsetneqq \mathbb{Q} \supsetneqq \mathbb{Z}

Showing proper superset relationships between power sets.

P(A)P(B)    ABP(A) \supsetneqq P(B) \iff A \supsetneqq B
P(A) \supsetneqq P(B) \iff A \supsetneqq B
