Merge Times and Hitting Times of Time-inhomogeneous Markov Chains
Concepts of Markov chains mixing, the study of the convergence to stationarity, emerged three decades ago. Studying times to convergence of Markov chains is crucial as it ties to many other mathematical areas, such as Markov ...
A Strategy and Honesty Based Comparison of Preferential Ballot Voting Methods
This paper presents an analysis of various preferential ballot voting systems based on the idea that voters should be encouraged to vote honestly and independently of the other votes cast. Random votes are simulated in three ...
Stochastic Study of Gerrymandering
In the 2012 election for the US House of Representatives, only four of North Carolina’s thirteen congressional districts elected a democrat, despite a majority democratic vote. This raises the question of whether gerrymandering, ...
A Stochastic Spatial Model for Tumor Growth
Evolutionary game theory can be used to study the interactions of different cell phenotypes and describe tumor population dynamics. Instead of killing tumor cells, clinical treatment could aim to change the nature of the ...
Relative Contribution of Common Jumps in Realized Correlation
This paper studies common intraday jumps and relative contribution of these common jumps in realized correlation between individual stocks and market index, using high-frequency price data. In introducing stochastic models ...
