precnapprox

Represents a negated relation combining precedence and approximate equality in mathematical notation.

Overview

Serves as a specialized mathematical operator combining the concepts of precedence and approximation with negation, primarily used in advanced mathematical proofs and formal logic.

  • Common in order theory and abstract algebra when discussing non-approximate precedence relationships
  • Useful for expressing complex mathematical statements where both ordering and approximation need to be precisely negated
  • Particularly relevant in theoretical computer science and mathematical logic when formal notations require explicit negation of combined relations

Examples

Showing that sequence A is not approximately precedes sequence B in a convergence analysis.

{an}{bn}\{a_n\} \precnapprox \{b_n\}
\{a_n\} \precnapprox \{b_n\}

Demonstrating non-approximate precedence between two functions in asymptotic analysis.

f(x)g(x) as xf(x) \precnapprox g(x) \text{ as } x \to \infty
f(x) \precnapprox g(x) \text{ as } x \to \infty
