A Geometrical Approach to Indefinite Least Squares Problems

Given Hilbert spaces ℋ and K , a (bounded) closed range operator C:H→K and a vector y∈K , consider the following indefinite least squares problem: find u∈ℋ such that 〈B(Cu−y),Cu−y〉=min x∈ℋ〈B(Cx−y),Cx−y, where B:K→K is a bounded selfadjoint operator. This work is devoted to give necessary and suffici...
