Direct parametrisation of invariant manifolds for non-autonomous forced systems including superharmonic resonances

Alessandra Vizzaccaro, Giorgio Gobat, Attilio Frangi +1

The direct parametrisation method for invariant manifold is a model-order reduction technique that can be applied to nonlinear systems described by PDEs and discretised e.g. with a…
