Indeed. But you still typically use the symbol ∞ when writing them.

I'm afraid I have no idea what Shubert calculus is - I guess a trip to
Wikipedia or Wolfram Alpha is in order... (And while I am aware of
Hilbert's list of problems, and know of a few, I don't have the full
list in my head - and I know that for several of them I can't begin to
comprehend the question, never mind the answer.)
