4) B. Let A = {u, v, w}, B = {x, y, z}. Determine whether the relation R = {(u, x), (v, z), (w, y)} from A to B is an injection function and surjection function?
What is the point of a partial order? a. We would like to generalize the properties of the relation x=yx=y to objects that are "basically the same," if not necessarily equal. b. We would like to generalize the properties of the relation x<yx<y to objects that do not naturally satisfy a total order in the way that numbers do. c. We would like to generalize the properties of the relation x≤yx≤y to objects that do not naturally satisfy a total order in the way that numbers do. d. There is no point. We make up mathematical objects for fun.
Decide whether the following relations are a partial order or not. Refer to the image below
Let A be a non-empty set, ≃ ⊆ A × A an equivalence realtionship and ⪯ ⊆ A × A a partial order, both over A. Consider the quotient set: A / ≃, and define the following relation ≪ ⊆ (A/ ≃) × (A/ ≃) where (S1, S2) ∈ ≪ if, and only if, there is an a ∈ S1 such that for all b ∈ S2, a ⪯ b. 1.) How to show that ≪r is is a partial order over A/ ≃ where ≪r is the reflex cause of ≪. 2.) Is it true that A has a minimal element according to ⪯ if, and only if, A/ ≃ has a minimal element according to≪r ? How to show if it is true or false (in such case suggest a counterexample)
For each of the following relations explain if it is: -Transitive -Partial Order -Total Order R is the relation over integers where (m,n) is in the relationship if the product of the digits in m is greater than or equal to the productof the digits in n.EG. m=1223 and n = 111111 is in the relation, but m=119and n= 2321is not in the relation.(1223 has product 12 and 111111 has product of 1)
Let σpo := (<) be the usual signature for strict partial orders. A linear order (A, <) is called dense if for any a, b ∈ A with a < b, there is c ∈ A such that a < c < b. a. Let σpo∞ := (<, { cn : n ∈ ℕ) and add axioms to DLO to get a theory DLO∞ axiomatizing the class of dense linear orders without endpoints that satisfy ci < ci+1 for all i ∈ ℕ. b. Provide three nonisomorphic countable models of DLO∞. Remark: In fact, DLO∞ has exactly three non-isomorphic countable models, but you do not need to prove this.
