While most of the results are already known, the proofs are somewhat new, and the paper can serve as a source for the estimates used in our paper on the analyticity of the Brownian intersection exponents (math.PR/0005295).22 pagesProbabilityMathematical Physics60J65Sharp estimates for Brownian non-intersection probabilitiestext
