Detailed Description

Interface to underlying groups for Hopf point calculations using the Moore-Spence formulation.

This abstract class provides the required interface for underlying groups to locate Hopf bifurcations using the bordering algorithm for the Moore-Spence Hopf fomulation (see LOCA::Hopf::MooreSpence::ExtendedGroup for a description of the governing equations).

This class is derived from the LOCA::TurningPoint::MooreSpence::AbstractGroup and LOCa::TimeDependent::AbstractGroup and declares several pure virtual methods for applying, solving, and computing derivatives of the complex matrix $ J+i\omega B$ where $ J$ is the Jacobian matrix, $ B$ is the mass matrix, and $\omega$ is a (real) scalar.
