Abstract: We study an extension to Krein spaces of the abstract interpolating spline problem in Hilbert spaces, introduced by M. Atteia. This is a quadratically constrained quadratic programming problem, where the objective function is not convex,… read more here.

Abstract: We study the problem of minimizing the ratio of quadratic functions with a quadratic constraint (QCRQ), which is a generation of the trust-region subproblem and covers the regularized total least square problem as a special… read more here.
