Gelation in Vector Multiplicative Coalescence and Extinction in Multi-Type Poisson Branching Processes
Heshan Aravinda, Yevgeniy Kovchegov, Peter T. Otto +1
In this note, we present a novel connection between a multi-type (vector) multiplicative coalescent process and a multi-type branching process with Poisson offspring distributions.…
Cross-Multiplicative Coalescent Processes and Applications
Yevgeniy Kovchegov, Peter T. Otto, Anatoly Yambartsev
We introduce and analyze a novel type of coalescent processes called cross-multiplicative coalescent that models a system with two types of particles, and . The bonds are fo…
The aggregate path coupling method for the Potts model on bipartite graph
Jose C. Hernandez, Yevgeniy Kovchegov, Peter T. Otto
In this paper, we derive the large deviations principle for the Potts model on the complete bipartite graph as increases to infinity. Next, for the Potts model on $K_…
Polynomial representation for the expected length of minimal spanning trees
Jared Nishikawa, Peter T. Otto, Colin Starr
In this paper, we investigate the polynomial integrand of an integral formula that yields the expected length of the minimal spanning tree of a graph whose edges are uniformly dist…
Path Coupling and Aggregate Path Coupling
Yevgeniy Kovchegov, Peter T. Otto
In this survey paper, we describe and characterize an extension to the classical path coupling method applied statistical mechanical models, referred to as aggregate path coupling.…
Rapid Mixing of Glauber Dynamics of Gibbs Ensembles via Aggregate Path Coupling and Large Deviations Methods
Yevgeniy Kovchegov, Peter T. Otto
In this paper, we present a novel extension to the classical path coupling method to statistical mechanical models which we refer to as aggregate path coupling. In conjunction with…
Mixing Times for the Mean-Field Blume-Capel Model via Aggregate Path Coupling
Yevgeniy Kovchegov, Peter T. Otto, Mathew Titus
In this paper we investigate the relationship between the mixing times of the Glauber dynamics of a statistical mechanical system with its thermodynamic equilibrium structure. For…
Asymptotic behavior of the finite-size magnetization as a function of the speed of approach to criticality
Richard S. Ellis, Jonathan Machta, Peter Tak-Hun Otto
The main focus of this paper is to determine whether the thermodynamic magnetization is a physically relevant estimator of the finite-size magnetization. This is done by comparing…
Analysis of phase transitions in the mean-field Blume-Emery-Griffiths model
Richard S. Ellis, Peter T. Otto, Hugo Touchette
In this paper we give a complete analysis of the phase transitions in the mean-field Blume-Emery-Griffiths lattice-spin model with respect to the canonical ensemble, showing both a…
