Processes with inert drift. (English) Zbl 1190.60079

Summary: We construct a stochastic process whose drift is a function of the process’s local time at a reflecting barrier. The process arose as a model of the interactions of a Brownian particle and an inert particle in a paper by F. B. Knight [Probab. Theory Relat. Fields 121, No. 4, 577–598 (2001; Zbl 1015.60072)]. We construct and give asymptotic results for two different arrangements of inert particles and Brownian particles, and construct the analogous process in higher dimensions.
