Random Growth Models
Share this pageEdited by Michael Damron; Firas Rassoul-Agha; Timo Seppäläinen
The study of random growth models began in probability theory
about 50 years ago, and today this area occupies a central place in
the subject. The considerable challenges posed by these models have
spurred the development of innovative probability theory and opened up
connections with several other parts of mathematics, such as partial
differential equations, integrable systems, and combinatorics. These
models also have applications to fields such as computer science,
biology, and physics.
This volume is based on lectures delivered at the 2017 AMS Short
Course “Random Growth Models”, held January 2–3,
2017 in Atlanta, GA.
The articles in this book give an introduction to the most-studied
models; namely, first- and last-passage percolation, the Eden model of
cell growth, and particle systems, focusing on the main research
questions and leading up to the celebrated Kardar-Parisi-Zhang
equation. Topics covered include asymptotic properties of infection
times, limiting shape results, fluctuation bounds, and geometrical
properties of geodesics, which are optimal paths for growth.
Readership
Graduate Students and researchers interested in various models of random growth in percolation theory, cell growth, and particle systems.
