\succeq
The symbol \succeq is used in mathematics to denote 'succeeds or is equal to' in a partial order. It is a binary relation that indicates one element is greater than or equal to another in terms of the order relation defined on a set.
Element x succeeds or is equal to element y in a partial order.
x \succeq y
Element a succeeds or is equal to b, and b succeeds or is equal to c, indicating a chain of relations in a partial order.
a \succeq b \succeq c
If p succeeds or is equal to q, then q is preceded or equal to p, showing the duality in order relations.
p \succeq q \Rightarrow q \preceq p
