In this note a matrix partial differential operator is considered. It is shown that under certain conditions it defines a closed operator with nonempty resolvent set, and its essential spectrum is determined. In the symmetric case G. D. RAIKOV obtained earlier corresponding results (under slightly d

In this paper we present a mixed ''multiple time scale -harmonic balance'' (MHB) method for a quite general non-linear oscillations problem subject to a periodic force. The MHB differs from the more traditional multiple time scale (MS) method in that it uses two separate procedures for the solutions
