Automatic Decoupling and Index-aware Model-Order Reduction for Nonlinear Differential-Algebraic Equations
Nicodemus Banagaaya, Giuseppe Ali, Sara Grundel +1
We extend the index-aware model-order reduction method to systems of nonlinear differential-algebraic equations with a special nonlinear term f(Ex), where E is a singular matrix. S…
Orientation Waves in a Director Field With Rotational Inertia
Giuseppe Ali, John K. Hunter
We study the propagation of orientation waves in a director field with rotational inertia and potential energy given by the Oseen-Frank energy functional from the continuum theory…
Diffractive Nonlinear Geometrical Optics for Variational Wave Equations and the Einstein Equations
Giuseppe Ali, John K. Hunter
We derive an asymptotic solution of the vacuum Einstein equations that describes the propagation and diffraction of a localized, large-amplitude, rapidly-varying gravitational wave…
Large amplitude gravitational waves
G. Ali, J. K. Hunter
We derive an asymptotic solution of the Einstein field equations which describes the propagation of a thin, large amplitude gravitational wave into a curved space-time. The resulti…
