Null controllability of Grushin-type operators in dimension two
We study the null controllability of the parabolic equation associated with the Grushin-type operator A = ∂ x+|x|∂ y , (γ > 0), in the rectangle Ω = (−1, 1) × (0, 1), under an additive control supported in an open subset ω of Ω. We prove that the equation is null controllable in any positive time for γ < 1 and that there is no time for which it is null controllable for γ > 1. In the transition ...
متن کاملNull controllability of degenerate parabolic equations of Grushin and Kolmogorov type
The goal of this note is to present the results of the references [5] and [4]. We study the null controllability of the parabolic equations associated with the Grushin-type operator ∂ x + |x|∂ y (γ > 0) in the rectangle (x, y) ∈ (−1, 1)×(0, 1) or with the Kolmogorov-type operator v∂xf+∂ vf (γ ∈ {1, 2}) in the rectangle (x, v) ∈ T×(−1, 1), under an additive control supported in an open subset ω ...
متن کاملNull controllability of Kolmogorov-type equations
We study the null controllability of Kolmogorov-type equations ∂t f + v ∂x f − ∂2 v f = u(t, x, v)1ω(x, v) in a rectangle , under an additive control supported in an open subset ω of . For γ = 1, with periodic-type boundary conditions, we prove that null controllability holds in any positive time, with any control support ω. This improves the previous result by Beauchard and Zuazua (Ann Ins H P...
متن کامل2D 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 ...
متن کاملOn Controllability and Near-controllability of Multi-input Discrete-time Bilinear Systems in Dimension Two
This paper completely solves the controllability problems of two-dimensional multi-input discrete-time bilinear systems with and without drift. Necessary and sufficient conditions for controllability, which cover the existing results, are obtained by using an algebraic method. Furthermore, for the uncontrollable systems, near-controllability is studied and necessary and sufficient conditions fo...
