This gives rise to a random composition of $n$. Assuming that the subordinator has the L\\'{e}vy measure, which behaves near zero like the gamma subordinator, we prove a law of the iterated logarithm for the number of blocks in the composition as $n$ tends to infinity. Along the way we prove a law of the iterated logarithm for the Lebesgue convolution of a standard Brownian motion and a deterministic regularly varying function. This result may be of independent interest.", "revisions": [ { "version": "v1", "updated": "2024-06-12T16:18:26.000Z" } ], "analyses": { "keywords": [ "iterated logarithm", "regenerative compositions", "gamma-like subordinators", "standard exponential distribution", "standard brownian motion" ], "note": { "typesetting": "TeX", "pages": 15, "language": "en", "license": "arXiv", "status": "editable" } } }
