Generalized Drazin-meromorphic pseudospectrum for multivalued linear relation

In this paperwe investigate the spectrum and Drazin their pseudo spectral analogues, for linear relations between Banach spaces corresponding spectra, generalized Drazinmeromorphic pseudospectrum. More specifically, Drazin-meromorphic pseudospectrum a on space is studied. We also make several observations about level set of relations. Furthermore, it shown that has no isolated points, finite number connected components each component contains an element from spectrum.
