Sparse learning of stochastic dynamical equations [PDF]
The Journal of Chemical Physics, 2018 With the rapid increase of available data for complex systems, there is great interest in the extraction of physically relevant information from massive datasets. Recently, a framework called Sparse Identification of Nonlinear Dynamics (SINDy) has been introduced to identify the governing equations of dynamical systems from simulation data.

New Hille Type and Ohriska Type Criteria for Nonlinear Third-Order Dynamic Equations
Mathematics, 2022 The objective of this paper is to derive new Hille type and Ohriska type criteria for third-order nonlinear dynamic functional equations in the form of a2(ζ)φα2a1ζφα1xΔ(ζ)ΔΔ+q(ζ)φαx(g(ζ))=0, on a time scale T, where Δ is the forward operator on T, α1, α2,

Oscillation of even order nonlinear dynamic equations on time-scales [PDF]
Mathematica Moravica, 2022 In this paper, the authors discuss the oscillatory behavior of solutions to a class of even order nonlinear dynamic equations on time scales. The results are established by a comparison with n-th order delay dynamic inequalities or first-order delay ...

Dynamics of relaxor ferroelectrics [PDF]
, 2000 We study a dynamic model of relaxor ferroelectrics based on the spherical random-bond---random-field model and the Langevin equations of motion. The solution to these equations is obtained in the long-time limit where the system reaches an equilibrium ...

An Efficient Policy Iteration Algorithm for Dynamic Programming Equations [PDF]
, 2015 We present an accelerated algorithm for the solution of static Hamilton-Jacobi-Bellman equations related to optimal control problems. Our scheme is based on a classic policy iteration procedure, which is known to have superlinear convergence in many ...
