A relational symbol combining succession and curly inequality to denote ordered structures in partial orders and lattice theory.
Examples
Partial ordering in a poset
x \succcurlyeq y \text{ if x dominates y}
Preference relation in economics
A \succcurlyeq B \text{ means bundle A is preferred to or indifferent to bundle B}
Comparing vectors componentwise
(x_1, x_2) \succcurlyeq (y_1, y_2) \iff x_1 \geq y_1 \text{ and } x_2 \geq y_2
