摘要

我们证明了滤波器、真滤波器和超滤波器的一个刻画定理，它是Łoś定理的一种逆。它比通常将这些项作为大坐标集的直觉更自然，这在超滤器的情况下实际上是不令人信服的。另外，我们得到了Łoś定理的一个非常简单的证明。

Compounding Objects

We prove a characterization theorem for filters, proper filters and ultrafilters which is a kind of converse of Łoś's theorem. It is more natural than the usual intuition of these terms as large sets of coordinates, which is actually unconvincing in the case of ultrafilters. As a bonus, we get a very simple proof of Łoś's theorem.
