چکیده

In this paper we study controllability properties of linear degenerate parabolic equations. Due to degeneracy, classical null controllability results do not hold in general. Thus we investigate results of 'regional null controllability', showing that we can drive the solution to rest at time T on a subset of the space domain, contained in the set where the equation is nondegenerate. keywords: linear degenerate equations, regional null controllability, persistent regional null controllability.

Null Controllability of Semilinear Degenerate Parabolic Equations in Bounded Domains

In this paper we study controllability properties for semilinear degenerate parabolic equations with nonlinearities involving the first derivative in a bounded domain of R. Due to degeneracy, classical null controllability results do not hold in general. Thus we investigate results of ’regional null controllability’, showing that we can drive the solution to rest at time T on a subset of the sp...

Persistent Regional Null Controllability for a Class of Degenerate Parabolic Equations

Motivated by physical models and the so-called Crocco equation, we study the controllability properties of a class of degenerate parabolic equations. Due to degeneracy, classical null controllability results do not hold for this problem in general. First, we prove that we can drive the solution to rest at time T in a suitable subset of the space domain (regional null controllability). However, ...

Null Controllability Results for Degenerate Parabolic Equations

The null controllability of parabolic operators in bounded domains, with both boundary or locally distributed controls, is a well-established property, see, e.g., (Bensoussan et al., 1993) and (Fattorini, 1998). Such a property brakes down, however, for degenerate parabolic operators even when degeneracy occurs on ”small” subsets of the space domain, such as subsets of the boundary. This talk w...

Exact Controllability of Nonlinear Diffusion Equations Arising in Reactor Dynamics

This paper studies the problems of local exact controllability of nonlinear and global exact null controllability of linear parabolic integro-differential equations respectively with mixed and Neumann boundary data with distributed controls acting on a subdomain ω of Ω ⊂ R. The proof of the linear problem relies on a Carleman-type estimate and observability inequality for the adjoint equations ...

2D Grushin-type equations: minimal time and null controllable data

We study internal null controllability for degenerate parabolic equations of Grushin-type Gγ = ∂ xx + |x|∂ yy, (γ > 0), in the rectangle (x, y) ∈ Ω = (−1, 1)× (0, 1). Previous works proved that null controllability holds for weak degeneracies (γ small), and fails for strong degeneracies (γ large). Moreover, in the transition regime and with strip shaped control domains, a positive minimal time ...
