Given a natural number c ∈ N. On natural numbers, the relation Rc is defined as follows: ∀ a, b ∈ N :  (a, b) ∈ Rc ⇔ (∃ u, v ∈ Z : au + bv = c) . In other words, two natural numbers are in the relation Rc just when the number c ∈ N can be written as their integer linear combination. a) Is the Rc session reflexive? b) Is the relation Rc symmetric? c) Is the Rc relation antisymmetric? d) Is the Rc session transitive?

Given a natural number c ∈ N. On natural numbers, the relation Rc is defined as follows:

a, b ∈ N :  (a, b) ∈ Rc ⇔ (∃ u, v ∈ Z : au + bv = c) .

In other words, two natural numbers are in the relation Rc just when the number c ∈ N can be written as their integer linear combination.

a) Is the Rc session reflexive?
b) Is the relation Rc symmetric?
c) Is the Rc relation antisymmetric?
d) Is the Rc session transitive?
The answers to all these questions must be duly substantiated, resp. proven.
