We bound the condition number of the Jacobian in pseudo-arclength continuation problems, and we quantify the effect of this condition number on the linear system solution in a Newton-GMRES solve. Pseudo-arclength continuation solves parameter dependent nonlinear equations G(u, λ) = 0 by introducing a new parameter s, which approximates arclength, and viewing the vector x = (u, λ) as a function of s. In this way simple fold singularities can be computed directly by solving a larger system F (x… CONTINUE READING
