Optimal response for stochastic differential equations in $T^{d}$ with perturbations on the drift term

Gianmarco Del Sarto, Franco Flandoli, Stefano Galatolo +2

We study stochastic differential equations on the $d$ -dimensional flat torus $T^{d}$ with drift and perturbation coefficients in $L^{\infty} (T^{d}; R^{d})$ and…

Divergence-kernel method for linear responses of densities and generative models

Angxiu Ni

We derive the divergence-kernel formula for the linear response of random dynamical systems. Specifically, the pathwise expression is for the parameter-derivative of the marginal o…

Optimal Response for Hyperbolic Systems by the fast adjoint response method

Stefano Galatolo, Angxiu Ni

In a uniformly hyperbolic system, we consider the problem of finding the optimal infinitesimal perturbation to apply to the system, from a certain set $P$ of feasible ones, to maxi…
