A variational principle for hypoelliptic equations with constant coefficients

, 2020
A variational method for solving hypoelliptic equations with constant coefficients of the following type: \[ \sum_{| \alpha | \leq m}a_{\alpha} D^{\alpha} u(x)=g(x),\quad x\in \Omega \subset R^ n;\quad \frac{\partial^ ju}{\partial n^ j}=0,\quad j=0,1,...,K,\quad x\in \partial \Omega. \] (\(\Omega\) is a bounded domain) is presented.
