Summary
This paper will define a new cardinal called aStationary Cardinal. We will show that every weakly∏ 11 -indescribable cardinal is a stationary cardinal, every stationary cardinal is a greatly Mahlo cardinal and every stationary set of a stationary cardinal reflects. On the other hand, the existence of such a cardinal is independent of that of a∏ 11 -indescribable cardinal and the existence of a cardinal such that every stationary set reflects is also independent of that of a stationary cardinal. As applications, we will show thatV=L implies ◊ 1 κ holds if κ is∏ 11 -indescribable and so forth.
