On the vectorial multifractal analysis in a metric space

open access: yesAIMS Mathematics, 2023
Multifractal analysis is typically used to describe objects possessing some type of scale invariance. During the last few decades, multifractal analysis has shown results of outstanding significance in theory and applications. In particular, it is widely

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 ...

On subcritical multi-type branching process in random environment [PDF]

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.

On statistical models on super trees

open access: yesJournal of High Energy Physics, 2018
We consider a particular example of interplay between statistical models related to CFT on one hand, and to the spectral properties of ODE, known as ODE/IS correspondence, on the other hand. We focus at the representation of wave functions of Schrödinger

Critical Branching Random Walks with Small Drift [PDF]

open access: yes, 2010
We study critical branching random walks (BRWs) $U^{(n)}$ on~$\mathbb{Z}_{+}$ where for each $n$, the displacement of an offspring from its parent has drift~$2\beta/\sqrt{n}$ towards the origin and reflection at the origin.

Branching random walks and multi-type contact-processes on the percolation cluster of ${\mathbb{Z}}^{d}$ [PDF]

open access: yes, 2015
In this paper we prove that, under the assumption of quasi-transitivity, if a branching random walk on ${{\mathbb{Z}}^d}$ survives locally (at arbitrarily large times there are individuals alive at the origin), then so does the same process when ...

Stochastic Dynamics of Proteins and the Action of Biological Molecular Machines

open access: yesEntropy, 2014
It is now well established that most if not all enzymatic proteins display a slow stochastic dynamics of transitions between a variety of conformational substates composing their native state.

Moment asymptotics for multitype branching random walks in random environment [PDF]

open access: yes, 2013
We study a discrete time multitype branching random walk on a finite space with finite set of types. Particles follow a Markov chain on the spatial space whereas offspring distributions are given by a random field that is fixed throughout the evolution ...
