Hi folks  could anyone think of a justification of the idea that if a function's arguments diverge (i.e. are taken to infinity), there's a high probability that the function too will diverge?
This would be really helpful for thinking about fundamental theories in particle physics, so any help much appreciated!

Not about "high probability", but if your function is nice enough, complex analysis could be of use. Liouville's theorem at least tells you that nonconstant differentiable functions [itex]\mathbb C \to \mathbb C[/itex] are unbounded. I'd guess there's some related machinery that would help more.

I agree with HallsofIvy, without some way to define a probability this does not work.
