Publicación Acceso abierto Caracterización de marcos en espacios 2-Hilbert(2022-09-03) Negrete Petro, Pedro Manuel; Ferrer Villar, OsminIn this research work we will give a characterization of two special classes of frames such as dual frames and Parseval frames in 2-Hilbert spaces, furthermore we will show some properties that transfer from frames in Hilbert spaces to frames in 2-Hilbert spaces. In addition we will give a necessary and sufficient condition for a countable sequence of vectors of a 2-Hilbert space to be a 2-frame of Parseval. Finally it will be shown how to construct 2-frames and 2-Parseval frames from some bounded operators.
