Optimal Prediction of Resistance and Support Levels under Constant Elasticity of Variance Processes
Ruibo Ma
Assuming that the asset price follows a constant elasticity of variance process, this paper studies the optimal prediction problem , w…
Susceptible-Infected Epidemics on Evolving Graphs at Critical Infection Rate
Wenze Chen, Haojie Hou, Ruibo Ma +1
Consider an SI process on a graph where each S--I connection becomes I--I at rate . Here S and I stand for ``susceptible'' and ``infected'' respectively. The evoSI model is…
A note on the cooperative two-type SIR processes on Galton-Watson trees
Ruibo Ma, Tai Heng Liu, Baghdadi Othmane +1
In the standard SIR model on a graph, infected vertices infect their neighbors at rate and recover at rate . We consider a two-type SIR process where each individual in the…
Complete convergence theorem for a two-level contact process
Ruibo Ma
We study a two-level contact process. We think of fleas living on a species of animals. The animals are a supercritical contact process in . The contact process acts…
Spatial heterogeneity can explain the stable coexistence of savanna and forest in South America
Rick Durrett, Ruibo Ma
In work with a variety of co-authors, Staver and Levin have argued that savanna and forest coexist as alternative stable states with discontinuous changes in density of trees at th…
