We consider a class of nonlinear distributed parameters retarded systems governed by differential-delay equations in a Hilbert space. The considered equations have separated linear parts and sublinear nonlinearities. Explicit conditions are established for the absolute stability. Moreover, it is shown that these conditions separate equations that satisfy the generalized AizermanMyshkis hypothesis.
Keywords: nonlinear distributed parameters retarded systems; absolute stability; the AizermanMyshkis problem.
