If β t is renormalized self-intersection local time for planar Brownian motion, we characterize when Ee γβ 1 is finite or infinite in terms of the best constant of a Gagliardo-Nirenberg inequality. We prove large deviation estimates for β 1 and -β 1 . We establish lim sup and lim inf laws of the iterated logarithm for β t as t → ∞.
