On the spectrum of the Sylvester-Rosenblum operator acting on triangular algebras
(Ele-Math, 2020)Let A and B be algebras and M be an A -B-bimodule. For A ∈ A , B ∈B, we define the Sylvester-Rosenblum operator τA,B :M →M via τA,B(M) = AM+MB for all M ∈ M . We investigate the spectrum of τA,B in three settings, namely: ...
