In this paper, we prove the interior approximate controllability of the impulsive semilinear
heat equation with delay in control and in state by proving first that the linear heat equation …

In this paper, a sufficient condition for the partial approximate controllability of semilinear
deterministic control systems is proved. Generally, the theorems on controllability are …

We discuss the controllability for a damped fractional differential system with impulses and
state delay, which involves Caputo fractional derivatives. Deriving the condition based on …

In this paper we apply Rothe's Fixed Point Theorem to prove the interior approximate
controllability of the following semilinear impulsive Heat Equation [...] where k= 1, 2,..., p, Ω is …

In this paper, we establish some important results for the impulsive wave equation. We begin
by proving the existence of a solution. Then, we study the impulse approximate …

In this paper, the partial S-controllability of semilinear partially observable control systems is
investigated. The essence of study is the presence of partial observations. We define a …

For many control systems in real life, impulses and delays are intrinsic properties that do not
modify their controllability. So we conjecture that under certain conditions the abrupt …

The main purpose of this article is to prove existence and uniqueness of the solutions for a
semilinear evolution equation with non-instantaneous impulses, delay and nonlocal …

The paper presents a survey of recent results in the area of controllability of second order
dynamical systems. Controllability problem for finite and infinite dimensional, linear …

For a broad class of control systems modeling real-life problems, delays and impulses are
natural properties that do not modify their behavior. So, we conjecture that under certain …
