We prove Pohozaev-type identities for smooth solutions of Euler-Lagrange equations of second and fourth order that arise from functional a depending on homogeneous Hörmander vector fields. We then exploit such integral identities to prove non-existence results for the associated boundary value problems.

由齐向矢量场驱动的微分算子的Pohozaev型恒等式
我们证明了二阶和四阶Euler-Lagrange方程的光滑解的Pohozaev型恒等式,该光滑解是由函数a取决于齐次Hörmander向量场产生的。然后,我们利用这些积分身份来证明相关边界值问题的不存在结果。
