“…We denote by u(t, x) = u(t, x; ϕ 0 ) the solution of the Initial Boundary Problem (IBP) (2), (3), (4). Note that, according to the theory of impulsive neural networks [20][21][22][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44], the solutions (2), (3), (4) are piecewise continuous functions that have jump discontinuities at the moments t k , k = 1, 2, . .…”
