"On the excursions of two-dimensional random walk and
Wiener process"
Endre Csáki, Antónia Földes,
Pál Révész and Zhan Shi
Summary: Consider a simple symmetric random walk
on the plane. Its portion between two consecutive
returns to zero are called excursions. We study the sum
of the excursions when the two largest ones are
eliminated from the sum. Similar investigations are
carried out for two-dimensional Wiener process.
Keywords: Planar random walk; local time;
excursions.
