N2 - It was shown by M. I. Zelikin (2007) that the spectrum of a nuclearoperator in a Hilbert space is central-symmetric i the traces of all odd powersof the operator equal zero. B. Mityagin (2016) generalized Zelikin's criteriumto the case of compact operators (in Banach spaces) some of which powers arenuclear, considering even a notion of so-called Zd-symmetry of spectra introducedby him. We study α-nuclear operators generated by the tensor elements of socalled α-projective tensor products of Banach spaces, introduced in the paper (αis a quasi-norm). We give exact generalizations of Zelikin's theorem to the casesof Zd-symmetry of spectra of α-nuclear operators (in particular, for s-nuclear andfor (r, p)-nuclear operators). We show that the results are optimal.
