conatus.expert.floquet_multipliers(solver, sol, n_modes, *, dense_max=2000, marginal_overlap_min=0.99, arnoldi_tol=REQUIRED)[source]

n_modes leading Floquet multipliers of S τ_ℓ J_T (monodromy of the discrete map, full space without the mean): dense if the active size ≤ dense_max (declared default), ARPACK otherwise with its required accuracy arnoldi_tol (k=: former name of n_modes). The marginal time and translation directions are identified by the overlap of the eigenvectors with v(u) and ∂x u (overlap > marginal_overlap_min, declared and returned), and counted.

Parameters:

  • sol (ECSSolution)

  • n_modes (int)

  • dense_max (int)

  • marginal_overlap_min (float)

  • arnoldi_tol (float)

Return type:
