Selfgravitating electroweak strings

Abstract: We obtain selfgravitating multi-string configurations for the Einstein–Weinberg–Salam model, in terms of solutions for a nonlinear elliptic system of Liouville type whose solvability was posed as an open problem in Yang (Solitons in Field Theory and Nonlinear Analysis, Springer, New York, 2001).
