| Feb 3, 2021 at 22:36 | comment | added | Evgeny Shinder | One thing which is relevant is that on normal varieties rational functions are regular away from their divisors of poles (see `Structure theorem' in III.8 in Mumford's red book), hence if a rational function is bounded on an open set, this set does not intersect the divisors of poles, and the function is regular. | |
