Prove that the set of all maximum size antichains of a poset P, forms a distributive lattice under "<" relation, where the relation between two maximum size antichains A and B is defined as follows: ABVA: 3y € B: x ≤py. Reminders: x ≤py means x ≤y in the poset P. . Remember to show that <, the relation between two maximum sized antichains as above, satisfies the conditions required to be a valid partial ordering relation.

Prove that the set of all maximum size antichains of a poset P, forms a distributive
lattice under "<" relation, where the relation between two maximum size antichains A and
B is defined as follows: AB VEA: Eye B:x≤py.
Reminders:
x <py means x ≤y in the poset P.
Remember to show that ≤, the relation between two maximum sized antichains as above,
satisfies the conditions required to be a valid partial ordering relation.
