On the distribution of ranked heights of excursions of a Brownian bridge

نویسنده

چکیده

The distribution of the sequence of ranked maximum and minimum values attained during excursions of a standard Brownian bridge (Bbr t ; 0 t 1) is described. The height M j of the jth highest maximum over a positive excursion of the bridge has the same distribution as M 1 =j, where the distribution of M 1 = sup0 t 1B br t is given by L evy's formula P (M br+ 1 > x) = e 2x . The probability density of the height M j of the jth highest maximum of excursions of the re ecting Brownian bridge (jB t j; 0 t 1) is given by a modi cation of the known -function series for the density of Mbr 1 = sup0 t 1 jB br t j. These results are obtained from a more general description of the distribution of ranked values of a homogeneous functional of excursions of the standardized bridge of a self-similar recurrent Markov process.

ON THE DISTRIBUTION OF RANKED HEIGHTS OF EXCURSIONS OF A BROWNIAN BRIDGE1 By Jim Pitman and Marc Yor

The distribution of the sequence of ranked maximum and minimum values attained during excursions of a standard Brownian bridge Bbr t 0 ≤ t ≤ 1 is described. The height Mbr+ j of the jth highest maximum over a positive excursion of the bridge has the same distribution as Mbr+ 1 /j, where the distribution of Mbr+ 1 = sup0≤t≤1 Bbr t is given by Lévy’s formula P Mbr+ 1 > x = e−2x 2 . The probabilit...

Lengths and heights of random walk excursions

Consider a simple symmetric random walk on the line. The parts of the random walk between consecutive returns to the origin are called excursions. The heights and lengths of these excursions can be arranged in decreasing order. In this paper we give the exact and limiting distributions of these ranked quantities. These results are analogues of the corresponding results of Pitman and Yor [10, 11...

A Superelastic Retrofitting Method for Mitigating the Effects of Seismic Excitations on Irregular Bridges

Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic response. As such, this paper proposes a new approach for balancing the ductility demand in irregular bridges by utilizing shape memory alloys (SM...

First Passage Time of Skew Brownian Motion

Nearly fifty years after the introduction of skew Brownian motion by Itô and McKean (1963), the first passage time distribution remains unknown. In this paper, we first generalize results of Pitman and Yor (2001) and Csáki and Hu (2004) to derive formulae for the distribution of ranked excursion heights of skew Brownian motion, and then use this result to derive the first passage time distribut...
