Add to ORKGAbstract. Matrix representations of bounded Hilbert space operators are considered. The matrices in question are defined with respect to frames, rather than bases. The frames, a generalisation of bases, used extensively in applied harmonic analysis, are overcomplete sequences. We consider some properties related to tight frames, where, up to some multi-plicative constant, a form of Parseval Identity takes place. We also describe parts of spectra of operators in terms of their matrices
