D. Bainov et al., STABILITY OF SOLUTIONS OF 1ST-ORDER IMPULSIVE PARTIAL-DIFFERENTIAL EQUATIONS, International journal of theoretical physics, 33(6), 1994, pp. 1359-1370
Theorems on stability and asymptotic stability of solutions of impulsi
ve partial differential equations of first order are proved. These res
ults are obtained via the method of differential inequalities and via
the method of Lyapunov functions.
