I want to verify certain inequalities involving real numbers and infinity. One case is showing certain expression is less than infinity. However, the following situation really puzzles me:
a = SR.var('a')
bool(a < infinity)
It returns 'false'. But when I do
assume(a < infinity)
It says
ValueError: Assumption is redundant
Why is this the case and how should I get 'True' for 'bool(a < infinity)'?
Thanks!
