Spectral Analysis of Preconditioned Matrices Arising from Stage-Parallel Implicit Runge–Kutta Methods of Arbitrarily High Order

I Dravins, S Serra-Capizzano, M Neytcheva - SIAM Journal on Matrix Analysis …, 2024 - SIAM
The use of high order fully implicit Runge–Kutta methods is of significant importance in the
context of the numerical solution of transient partial differential equations, in particular when …

A stabilization of a continuous limit of the ensemble Kalman inversion

D Armbruster, M Herty, G Visconti - SIAM Journal on Numerical Analysis, 2022 - SIAM
The ensemble Kalman filter (EnKF) belongs to the class of iterative particle filtering methods
and can be used for solving control-to-observable inverse problems. In this context, the …

Bistability of equilibria and the 2-tori dynamics in an endogenous growth model undergoing the cusp–Hopf singularity

G Bella, P Mattana - Nonlinear Analysis: Real World Applications, 2018 - Elsevier
This paper studies the properties of bistability of equilibria, giving rise to periodic oscillations
and 2-tori chaotic dynamics in the full three-dimensional structure of the generalized version …

Non-resonant double Hopf bifurcations: The complex case

GR Itovich, JL Moiola - Journal of Sound and Vibration, 2009 - Elsevier
The analysis of the unfolding of a non-resonant double Hopf singularity is considered using
the frequency domain and the normal form methodologies. A higher-order harmonic balance …
