Depends on the mathematical framework you're working with.... there's a genre in theoretical compsci that deals with parallel algorithms, and as a toy example, I remember an O(1) sorting algo (given O(n^2) processors). This example is more fun than anything, but ofc in general you're free what constraints you subject your statements to.
