Consistency and convergence rate of phylogenetic inference via regularization. [PDF]

open access: yesAnn Stat, 2018
It is common in phylogenetics to have some, perhaps partial, information about the overall evolutionary tree of a group of organisms and wish to find an evolutionary tree of a specific gene for those organisms.

Convergence Rate Estimates for the Low Mach and Alfv\'en Number Three-Scale Singular Limit of Compressible Ideal Magnetohydrodynamics [PDF]

open access: yes, 2020
Convergence rate estimates are obtained for singular limits of the compressible ideal magnetohydrodynamics equations, in which the Mach and Alfv\'en numbers tend to zero at different rates. The proofs use a detailed analysis of exact and approximate fast,

Convergence Rates in Uniform Ergodicity by Hitting Times and $$L^2$$-Exponential Convergence Rates [PDF]

open access: yesJournal of Theoretical Probability, 2022
Generally the convergence rate in exponential ergodicity $ $ is an upper bound for the convergence rate $ $ in uniform ergodicity for a Markov process, that is $ \geqslant $. In this paper, we prove that $ \geqslant \inf \{lambda,1/M_H\}$, where $M_H$ is a uniform bound on the moment of the hitting time to a "compact" set $H$.

Convergence rates of Gaussian ODE filters [PDF]

open access: yesStatistics and Computing, 2020
AbstractA recently introduced class of probabilistic (uncertainty-aware) solvers for ordinary differential equations (ODEs) applies Gaussian (Kalman) filtering to initial value problems. These methods model the true solutionxand its firstqderivativesa priorias a Gauss–Markov process$${\varvec{X}}$$X, which is then iteratively conditioned on information

Convergence Rate Analysis [PDF]

open access: yes, 2009
After showing the convergence of the two numerical methods for Frobenius-Perron operators in the previous chapter, we further investigate the convergence rate problem for them. Keller’s stochastic stability result for a class of Markov operators will be studied first, which leads to his first proof of the L1-norm convergence rate O(ln n/n) for Ulam’s ...

The convergence rate of approximate solutions for nonlinear scalar conservation laws [PDF]

open access: yes, 1992
The convergence rate is discussed of approximate solutions for the nonlinear scalar conservation law. The linear convergence theory is extended into a weak regime. The extension is based on the usual two ingredients of stability and consistency.

Rate of Convergence for Cardy’s Formula [PDF]

open access: yesCommunications in Mathematical Physics, 2014
We show that crossing probabilities in 2D critical site percolation on the triangular lattice in a piecewise analytic Jordan domain converge with power law rate in the mesh size to their limit given by the Cardy-Smirnov formula. We use this result to obtain new upper and lower bounds of exp(O(sqrt(log log R))) R^(-1/3) for the probability that the ...

Rate of Convergence Towards Hartree Dynamics

open access: yes, 2011
We consider a system of N bosons interacting through a two-body potential with, possibly, Coulomb-type singularities. We show that the difference between the many-body Schr\"odinger evolution in the mean-field regime and the effective nonlinear Hartree ...
