Remarks on the Convex Minorant of Brownian Motion

  • Chapter

Part of the book series: Progress in Probability and Statistics ((PRPR,volume 5))

Abstract

Recently Groeneboom [1] studied the concave majorant process of a Brownian motion (Bt, t ≤ O). The purpose of this note is to take a fresh look at some of Groeneboom’s results in the context of path decompositions of Williams [7], and to give a simple new description of this concave majorant process.
