Abstract: We extend a sequential quadratic programming method for equality constrained optimization
to the setting of Hilbert manifolds. The use of retractions and stratifications allow us to pull back the functional
and the constraint mapping to linear spaces and then linearize the problem. We study local quadratic convergence
to minimizers. In addition, we present a composite step method for globalization based on cubic regularization of the
objective function and affine covariant damped Newton method for feasibility and show transition to fast local convergence.
We test our method on equilibrium problem in elasticity where an inextensible elastic rod under dead loads is simulated.
Then we present an optimal control problem for this model.
