The well known problem stated by M. A. Aizer-man several decades ago consists of the comparison of the linear stability (Hurwitz) and absolute stability sectors in systems with sector restricted nonlinearities. This problem remains a test of the sharpness ("degree of conservatism") of...
A new case when the third-order Fitts counterexample to Aizerman's conjecture is incorrect has been found.
It is shown that Fitts' third-order counterexample to Aizerman's conjecture is false for some values of the parameters.
