Снежана Христова, Кремена Стефанова, Лиляна Ванкова - В работата са решени няколко нови видове линейни дискретни неравенства, които съдържат максимума на неизвестната функция в отминал интервал от време. Някои от тези неравенства са приложени за изучаване непрекъснатата зависимост от смущения при дискретни уравнения с максимуми. Several new types of linear discrete inequalities containing the maximum of the unknown function over a past time interval are solved. Some of these...

In the paper sufficient conditions for the difference equation : Δxn = Σi=0 r an (i) xn+i to have a solution which tends to a constant, are given. Applying these conditions, an asymptotic formula for a solution of an m-th order equation is presented.
