We discuss the problem of absolute stability and the Aizerman conjecture. Necessary and sufficient conditions are derived for the Lurie-Postnikov system to be absolutely stable by using a G-type Lyapunov function. The conditions that we give will be easily verified in practical applications.

## Abstract A necessary condition for the existence of a circuit of any specified length in a connected planar graph is developed and several applications of this result are given. This necessary condition is a direct generalization of the Kosyrev‐Grinberg condition for the existence of a Hamiltoni
