How to say when a university was established
创建于

建立于

创立于

创办于

are all acceptable, but for university I believe 创立于 is the most accurate one, the 立 here adds a subtle preeminence hint, and the 创 implies hard working.

In contrast, 创办于 does not have the "greatness" flavor, and 建立于 can be used for any institute in general.

I don't think there is an abbreviation that can convey the same implications.
