Asymptotic description of a test particle around a Schwarzschild black hole
(Institute of Physics Publishing, 2018)
Asymptotic Behavior for a nonlocal diffusion equation on the half line
(Amer Inst Mathematical Sciences, 2015-04)
We study the large time behavior of solutions to a nonlocal diffusion equation, ut=J∗u−u with J smooth, radially symmetric and compactly supported, posed in R+ with zero Dirichlet boundary conditions. In the far-field ...
Asymptotic Behavior for a Nonlocal Diffusion Equation in Domains with Holes
(Springer, 2012-08)
The paper deals with the asymptotic behavior of solutions to a non-local diffusion equation, ut = J ∗u −u := Lu, in an exterior domain, Ω, which excludes one or several holes, and with zero Dirichlet data on RN \Ω. When ...
Near-field asymptotics for the porous medium equation in exterior domains: The critical two-dimensional case
(Society for Industrial and Applied Mathematics, 2018-09)
We consider the porous medium equation in an exterior two-dimensional domain that excludes a hole, with zero Dirichlet data on its boundary. Gilding and Goncerzewicz proved in 2007 that in the far-field scale, which is the ...
Large sample properties of an optimization-based matching
(Universidad de Chile, Facultad de Economía y Negocios, 2014)
This paper mainly concerns the the asymptotic properties of the BLOP matching estimator
introduced by D´ıaz, Rau & Rivera (Forthcoming), showing that this estimator of the ATE attains
the standard limit properties, and ...
C 3 matching for asymptotically flat spacetimes
(Institute of Physics Publishing, 2019)
We propose a criterion for finding the minimum distance at which an interior solution of Einstein's equations can be matched with an exterior asymptotically flat solution. The location of the matching hypersurface is thus ...
Testing viscoelastic numerical schemes using the Oldroyd-B fluid in Newtonian kinematics
(Elsevier B.V., 2020-12-15)
We focus here on using a Newtonian velocity field to evaluate numerical schemes for two different formulations of viscoelastic flow. The two distinct formulations we consider, correspond to either using a fixed basis for ...
Matching estimators with few treated and many control observations
(2018-09)
We analyze the properties of matching estimators when there are few treated, but many control observations. We show that, under standard assumptions, the nearest neighbor matching estimator for the average treatment effect ...
Robust randomized matchings
(Informs, 2018-05)
The following game is played on a weighted graph: Alice selects a matching M and Bob selects a number k. Alice's payoff is the ratio of the weight of the k heaviest edges of M to the maximum weight of a matching of size ...
Optimal Boussinesq model for shallow-water waves interacting with a microstructure
(2007-10-12)
In this paper, we consider the propagation of water waves in a long-wave asymptotic regime, when the bottom topography is periodic on a short length scale. We perform a multiscale asymptotic analysis of the full potential ...
