We present a scheme for the determination of control Lyapunov functions which can be used as a basis for numerical computations. Under the assumption of local asymptotic nullcontrollability we de ne the domain of asymptotic nullcontrollability. On this set a control Lyapunov function is de ned via an optimal control problem. It is then shown that this function can be characterized as the unique...

Effects of the tertiary amines, procaine and lidocaine, its quaternary derivative QX—314, and neutral benzocaine, on Na currents in internally perfused neuro-blastoma cells were studied using the suction-pipette voltage clamp technique (Kostyuk et al. 1975 ; Zubov et al. 1980). Neuroblastoma cells used were N18 A-l and NTR-1 subclones derived from C1300 line (Konobasova et al. 1981) and Neuro 2...
