In summary, a ring that is both left Artinian and right Noetherian is also right Artinian. This means that every descending chain of its left ideals stabilizes, and every ascending chain of its right ideals also stabilizes. Therefore, there is a k value such that In+1 = In for all n ≥ k, indicating that the ring is also right Artinian.

A left Artinian ring R is a ring for which every descending chain R=I0 ⊃I1 ⊃I2 ⊃…⊃In ⊃… of its left ideals stabilizes, i.e. there is a k such that In+1 =In for all n≥k

A right Noetherian ring R is ring in which every ascending chain of right ideals stabalizes

So if a ring is left Artinian and right Noetherian, what can you say? What would you like to have happen to conclude that this ring is also right Artinian?

When you post a question here, include information like what you have below in your initial post. That's why the 2nd section on relevant equations and definitions is there in the template. It should just be erased.

What is an Artinian ring?

An Artinian ring is a ring that satisfies the descending chain condition on left or right ideals, meaning that for any sequence of ideals I1
