Title: A gluing construction of singular solutions for a fully non-linear equation in conformal geometry.
Abstract: We study construction of a complete non-compact Riemannian metrics with positive constant σ2-curvature, on the sphere Sn with a prescribed singular set Λ given by a disjoint union of closed submanifolds whose dimension is positive and strictly less than n−√n−22 .
This is a fully non-linear problem, nevertheless, we show that the classical gluing method of Mazzeo-Pacard for the scalar curvature still works in this setting since the linearized operator has good mapping properties in weighted spaces. A necessary condition is that 2 ≤ 2k < n.
