Delay and Memory-Type Null Controllability for Heat Equations in Finite Dimensions

Dev Prakash Jha, Raju K. George

We study null controllability for linear heat-type systems in finite dimensions that incorporate both memory and time-delay effects. A strengthened notion of controllability, refer…

Memory-Type Null Controllability of Parabolic Equations with Moving Controls: A Geometric Characterization

Dev Prakash Jha, Raju K. George

We study memory-type null controllability for linear parabolic equations with hereditary terms and time-dependent control regions. In contrast with classical null controllability,…

Exact Null Controllability of Non-Autonomous Conformable Fractional Semi-Linear Systems with Nonlocal Conditions

Dev Prakash Jha, Raju K. George

We study the exact null controllability of a class of non-autonomous conformable fractional semi-linear evolution systems with nonlocal initial conditions in Hilbert spaces. The an…
