A direct method for the characterization and computation of bifurcation points with corank 2
An extension of a direct method due to \textit{A. Griewank} and \textit{G. W. Reddien} [SIAM J. Numer. Anal. 21, 176-185 (1984; Zbl 0536.65031)] for the characterization and computation of double singular points with corank 2 is presented. Singular points which satisfy a certain type of symmetry are also considered. Conditions under which the augmented system is uniquely solvable at the bifurcation point are presented. Numerical results to demonstrate the efficiency of the method are also discussed.
