gvertneqq

Represents a strict greater-than relation with a vertical line and two parallel horizontal lines, used in advanced mathematical notation.

Overview

Serves as a specialized comparison operator in mathematical logic and set theory, particularly when standard inequality symbols are insufficient to express precise relationships.

  • Common in formal mathematical proofs and advanced algebra
  • Used to denote specific types of ordered relationships
  • Often appears alongside other specialized comparison operators in advanced mathematical texts
  • Particularly useful in contexts where multiple distinct types of inequalities need to be distinguished

Examples

Comparing two sequences that are strictly greater and not equal.

{an}{bn} for all nN\{a_n\} \gvertneqq \{b_n\} \text{ for all } n \in \mathbb{N}
\{a_n\} \gvertneqq \{b_n\} \text{ for all } n \in \mathbb{N}

Expressing strict inequality between two sets.

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

Showing strict ordering in measure theory.

μ(E1)μ(E2)\mu(E_1) \gvertneqq \mu(E_2)
\mu(E_1) \gvertneqq \mu(E_2)
