Abstract:
A definition of frames for Krein spaces is proposed, which extends the notion of . J-orthonormal bases of Krein spaces. A . J-frame for a Krein space . (H,[,]) is in particular a frame for . H in the Hilbert space sense. But it is also compatible with the indefinite inner product [. , . ], meaning that it determines a pair of maximal uniformly . J-definite subspaces, an analogue to the maximal dual pair associated to a . J-orthonormal basis.Also, each . J-frame induces an indefinite reconstruction formula for the vectors in . H, which resembles the one given by a . J-orthonormal basis. © 2012 Elsevier Ltd.
