Generalized Weyl theorem and tensor product. (English) Zbl 1288.47020
Ukr. Math. J. 64, No. 9, 1464-1474 (2013); translation from Ukr. Mat. Zh. 64, No. 9, 1289-1296 (2012).
The author considers relations between different types of spectra of linear operators $$A, B$$ and their tensor product $$A\otimes B$$. In particular, he proves a generalized $$a$$-Browder theorem, a generalized $$a$$-Weyl theorem, and the so-called $$(gw)$$ property for $$A\otimes B$$.
