Spatially Inhomogeneous Evolutionary Games

open access: yesCommunications on Pure and Applied Mathematics, Volume 74, Issue 7, Page 1353-1402, July 2021., 2021
Abstract We introduce and study a mean‐field model for a system of spatially distributed players interacting through an evolutionary game driven by a replicator dynamics. Strategies evolve by a replicator dynamics influenced by the position and the interaction between different players and return a feedback on the velocity field guiding their motion ...

Consistent Inversion of Noisy Non‐Abelian X‐Ray Transforms

open access: yesCommunications on Pure and Applied Mathematics, Volume 74, Issue 5, Page 1045-1099, May 2021., 2021
Abstract For M a simple surface, the nonlinear statistical inverse problem of recovering a matrix field from discrete, noisy measurements of the SO(n)‐valued scattering data CΦ of a solution of a matrix ODE is considered (n ≥ 2). Injectivity of the map Φ ↦ CΦ was established by Paternain, Salo, and Uhlmann in 2012.

Lippmann‐Schwinger solvers for the computational homogenization of materials with pores

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 121, Issue 22, Page 5017-5041, 30 November 2020., 2020
Summary We show that under suitable hypotheses on the nonporous material law and a geometric regularity condition on the pore space, Moulinec‐Suquet's basic solution scheme converges linearly. We also discuss for which derived solvers a (super)linear convergence behavior may be obtained, and for which such results do not hold, in general.

A New Class of Difference Methods with Intrinsic Parallelism for Burgers–Fisher Equation

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This paper proposes a new class of difference methods with intrinsic parallelism for solving the Burgers–Fisher equation. A new class of parallel difference schemes of pure alternating segment explicit‐implicit (PASE‐I) and pure alternating segment implicit‐explicit (PASI‐E) are constructed by taking simple classical explicit and implicit schemes ...

Verified Error Bounds for Real Eigenvalues of Real Symmetric and Persymmetric Matrices

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This paper mainly investigates the verification of real eigenvalues of the real symmetric and persymmetric matrices. For a real symmetric or persymmetric matrix, we use eig code in Matlab to obtain its real eigenvalues on the basis of numerical computation and provide an algorithm to compute verified error bound such that there exists a perturbation ...

Discretization of Poincaré map

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2013
We analytically study the relationship between the Poincaré map and its one step discretization. Error estimates are established depending basically on the right hand side function of the investigated ODE and the given numerical scheme. Our basic tool is

Semilocal analysis of equations with smooth operators

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
Recent work on semilocal analysis of nonlinear operator equations is informally reviewed. A refined version of the Kantorovich theorem for Newton's method, with new error bounds, is presented. Related topics are briefly surveyed.

Identification and estimation of continuous‐time dynamic discrete choice games

open access: yesQuantitative Economics, Volume 17, Issue 1, Page 254-296, January 2026.
This paper considers the theoretical, computational, and econometric properties of continuous‐time dynamic discrete choice games with stochastically sequential moves, introduced by Arcidiacono, Bayer, Blevins, and Ellickson (2016). We consider identification of the rate of move arrivals, which was assumed to be known in previous work, as well as a ...
