In this paper we study global Gevrey/analytic hypoellipticity of the anisotropic twisted Laplacian L(p,q), depending on the powers p_j , q_j , 1 ≤ j ≤ n, which determine the anisotropy. It turns out that when p_j = q_j = 1 for all j (the case of the “classical” twisted Laplacian) then the anisotropic twisted Laplacian is globally analytic hypoelliptic, whereas when for at least one j either p_j > 1 or q_j > 1, the operator L(p,q) is globally Gevrey σ,τ hypoelliptic, for suitable multi-indices σ and τ.

Abstract

In this paper we study global Gevrey/analytic hypoellipticity of the anisotropic twisted Laplacian L(p,q), depending on the powers p_j , q_j , 1 ≤ j ≤ n, which determine the anisotropy. It turns out that when p_j = q_j = 1 for all j (the case of the “classical” twisted Laplacian) then the anisotropic twisted Laplacian is globally analytic hypoelliptic, whereas when for at least one j either p_j > 1 or q_j > 1, the operator L(p,q) is globally Gevrey σ,τ hypoelliptic, for suitable multi-indices σ and τ.
