Martingales and the fixation time of evolutionary graphs with arbitrary dimensionality

open access: yesRoyal Society Open Science, 2022
Evolutionary graph theory (EGT) investigates the Moran birth–death process constrained by graphs. Its two principal goals are to find the fixation probability and time for some initial population of mutants on the graph.

Martingales and the characteristic functions of absorption time on bipartite graphs

open access: yesRoyal Society Open Science, 2021
Evolutionary graph theory investigates how spatial constraints affect processes that model evolutionary selection, e.g. the Moran process. Its principal goals are to find the fixation probability and the conditional distributions of fixation time, and ...

The Basic Reproduction Number for the Markovian SIR-Type Epidemic Models: Comparison and Consistency

open access: yesJournal of Mathematics, 2022
This paper is concerned with a well-known epidemiological concept to measure the spread of infectious disease, that is, the basic reproduction number. This paper has two major objectives.

A Divergent, Two-Parameter, Bounded Martingale [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
An example is given of a divergent, uniformly bounded martingale X = { X t : t ∈ T } X = \{ {X_t}:t \in T\} where the index t ranges over the set T of pairs of positive integers with the usual coordinatewise ordering.

A new efficient method to detect genetic interactions for lung cancer GWAS

open access: yesBMC Medical Genomics, 2020
Background Genome-wide association studies (GWAS) have proven successful in predicting genetic risk of disease using single-locus models; however, identifying single nucleotide polymorphism (SNP) interactions at the genome-wide scale is limited due to ...

Littlewood-Paley theory for triangle buildings [PDF]

open access: yes, 2017
For the natural two parameter filtration $(\mathcal{F}_\lambda : \lambda \in P)$ on the boundary of a triangle building we define a maximal function and a square function and show their boundedness on $L^p(\Omega_0)$ for $p \in (1, \infty)$.

On two-parameter non-degenerate brownian martingales

open access: yesBulletin des Sciences Mathématiques, 1998
In the first part of the paper the authors study the existence and the properties of the density of the two-parameter Brownian martingale \(N(z)= \int_{[0,T]^2} G(\zeta) dW(\zeta)\), \(z \in [0,T]^2\), driven by a Brownian sheet \(\{W(z), z\in [0,T]^2\}\), and with a square-integrable adapted process \(G\) as integrand verifying, in addition to the ...

Doob's maximal identity, multiplicative decompositions and enlargements of filtrations [PDF]

open access: yes, 2006
In the theory of progressive enlargements of filtrations, the supermartingale $Z_{t}=\mathbf{P}(g>t\mid \mathcal{F}_{t}) $ associated with an honest time g, and its additive (Doob-Meyer) decomposition, play an essential role. In this paper, we propose an

Optimal dual martingales, their analysis and application to new algorithms for Bermudan products [PDF]

open access: yes, 2012
In this paper we introduce and study the concept of optimal and surely optimal dual martingales in the context of dual valuation of Bermudan options, and outline the development of new algorithms in this context.
