T2 ⇒ KC ⇒ US ⇒ T1
In a topological KC-space, every compact space is closed.
In a US-space, each convergent sequence has a unique limit.
So, T2 ⇒ KC ⇒ US ⇒ T1, but the converse implications do not hold.
(a): Can yo …

I have reached a deadlock to find a example to show that a compact Hausdorff space does not need to have a no non-trivial convergent sequence.(except $\beta\omega$)
can you give me a example of …
