A relational symbol representing "greater than or approximately equal to" commonly used in inequalities and numerical comparisons.
Examples
Comparing asymptotic behavior
f(n) \gtrsim n^2 \text{ as } n \to \infty
Inequality with approximation in physics
E \gtrsim mc^2 + \frac{p^2}{2m}
Statistical comparison
P(X > \mu) \gtrsim 0.5
