Coalescing-Branching Random Walks on Graphs [PDF]

open access: yesACM Transactions on Parallel Computing, 2013
We study a distributed randomized information propagation mechanism in networks we call the coalescing-branching random walk (cobra walk, for short). A cobra walk is a generalization of the well-studied “standard” random walk, and is useful in modeling and understanding the Susceptible-Infected- Susceptible (SIS ...

A Note on the Transience of Critical Branching Random Walks on the Line [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
Gantert and Müller (2006) proved that a critical branching random walk (BRW) on the integer lattice is transient by analyzing this problem within the more general framework of branching Markov chains and making use of Lyapunov functions. The main purpose

Patchy nuclear chain reactions

open access: yesCommunications Physics, 2021
Understanding and predicting fluctuations of the neutron population within a nuclear reactor is of fundamental importance for nuclear safety, especially in connection with reactor control at startup and shutdown.

Some Criteria for the Transience of Simple Random Walks on Trees [PDF]

open access: yesThe Egyptian Statistical Journal, 1991
The main object of this paper is to use the connection between random walks and electrical networks to obtain much simpler proofs for the results on transience and volumes of trees, given in [7], than Woess' proofs.

Exact Derivation of a Finite-Size Scaling Law and Corrections to Scaling in the Geometric Galton-Watson Process. [PDF]

open access: yesPLoS ONE, 2016
The theory of finite-size scaling explains how the singular behavior of thermodynamic quantities in the critical point of a phase transition emerges when the size of the system becomes infinite. Usually, this theory is presented in a phenomenological way.

Note on the Generalized Branching Random Walk on the Galton–Watson Tree

open access: yesFractal and Fractional, 2023
Let ∂T be a super-critical Galton–Watson tree. Recently, the first author computed almost surely and simultaneously the Hausdorff dimensions of the sets of infinite branches of the boundary of ∂T along which the sequence SnX(t)/SnX˜(t) has a given set of

Algorithm for branching and population control in correlated sampling

open access: yesPhysical Review Research, 2023
Correlated sampling has wide-ranging applications in Monte Carlo calculations. When branching random walks are involved, as commonly found in many algorithms in quantum physics and electronic structure, population control is typically not applied with ...

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
We investigate a multi-type Galton-Watson process in a random environment generated by a sequence of independent identically distributed random variables.
