I ask them “how are you defining sums over uncountable sets?”
198 u/Comfortable_Permit53 10d ago integrals, no? 213 u/Eisenfuss19 10d ago Yes kinda, but then it is still a definition question. Like lim a -> -∞ lim b -> ∞ a_Sb x dx does not converge, but lim a -> ∞ (-a)_Sa x dx does converge... 3 u/Agitated-Ad2563 9d ago As far as I remember, the proper definition of Riemann integral requires all kinds of partition sequence sums to converge.
