Stochastic Allen-Cahn equation with mobility
Lorenzo Bertini, Paolo Buttà, Adriano Pisante
We introduce a class of stochastic Allen-Cahn equations with a mobility coefficient and colored noise. For initial data with finite free energy, we analyze the corresponding Cauchy…
Front fluctuations for the stochastic Cahn-Hilliard equation
L. Bertini, S. Brassesco, P. Buttà
We consider the Cahn-Hilliard equation in one space dimension, perturbed by the derivative of a space and time white noise of intensity , and we investigate the effec…
Computing the structured pseudospectrum of a Toeplitz matrix and its extreme points
Paolo Buttà, Nicola Guglielmi, Silvia Noschese
The computation of the structured pseudospectral abscissa and radius (with respect to the Frobenius norm) of a Toeplitz matrix is discussed and two algorithms based on a low rank p…
Resonances and O-curves in Hamiltonian systems
Paolo Buttà, Piero Negrini
We investigate the problem of the existence of trajectories asymptotic to elliptic equilibria of Hamiltonian systems in the presence of resonances.
