The design problem of a high-gain observer is considered for some 2× 2 and 3× 3
semilinear reaction-diffusion systems, with possibly distinct diffusivities, and considering …

This paper aims to study the approximate controllability of semilinear population dynamics
system with diffusion using semigroup theory. The semilinear population dynamical model …

This thesis introduces some non-trivial extensions of the classical high-gain observer design
for finite-dimensional nonlinear systems to some classes of infinite-dimensional systems …

Using the fundamentals of functional differential equations, we provide explicit controllability
results for a family of semilinear nonautonomous predator-prey systems in this study. The …

In this paper, the approximate controllability of an abstract model of stochastic semilinear
reaction diffusion equation in Hilbert spaces is considered. The existence and uniqueness of …
