- Let A = {0,1,2,3} and R a relation over A: R = {(0,0),(0,1),(0,3),(1,1),(1,0),(2,3),(3,3)} Check whether R is an equivalence relation or a partial order. Give a counterexample in each case in which the relation does not satisfy one of the properties of being an equivalence relation or a partial order.arrow_forwardLet 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. Write down a σpo -theory DLO axiomatizing the class of all dense linear order without endpoints (i.e. without a least / largest elements). b. Verify that (ℚ, <) is a countable (if it is finite or admits a bijection to ℕ) model of DLO. You may use that ℚ is countable without proof. Note: It is a theorem that DLO has only one countable model up to isomorphism, i.e. all countable models are isomorphic to each other.arrow_forwardWhich of these relations on the set {0, 1, 2, 3} are equivalence relations?

- Let R be a relation over a set A = {a,b,c,d}. What kind of order is R? Note: Select the order that it satisfies the most properties for. That is, if the relation is a partial order, then it's also technically a preorder; but partial order will be correct, and preorder will be an incorrect response. If the relation doesn't satisfy all of the properties for any of the listed orders, then select "None of these".

How many possible symmetric relations over A contain the ordered pairs (2, 3), (3, 2), (4, 7), (5, 5) and (8, 7)?arrow_forwardConsider the partial order with domain{3,5,6,7,10,14,20,30,60}and with x ≤ y if x evenly divides y.

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.arrow_forward
