Controllability Problems for the Heat Equation with Variable Coefficients on a Half-Axis Controlled by the Neumann Boundary Condition

Larissa Fardigola, Kateryna Khalina

In the paper, the problems of controllability and approximate controllability are studied for the control system $w_t=\frac{1}{\rho }{\left(k{w}_x\right)}_x+\gamma w$, $\left.\left(\sqrt{\frac{k}ρ…
