∞-connections on principal ∞-bundles over ∞-Lie groups $G$.

Summary: Quantum Lower Bound for the Collision Problem
Scott Aaronson #
The collision problem is to decide whether a function X :
{1, . . . , n} # {1, . . . , n} is onetoone or twotoone, given
that one of these is the case. We show a lower bound of

Modulo arithmetic (?) question
First transition :
Binomial expansion
Second transition :
Cancelling 1 from both sides
Third Transition :
Take 80 common on the LHS and divide both sides by 5
Fourth Transition :
divide both sides by 16 (2^4 = 16)
