报告摘要:We will consider polyharmonic equations $\Delta^m u = \pm u^p$ in ${\mathbb R}^n$ for all $n, m \in {\mathbb N}^*$ and $p \in {\mathbb R}$. We study the existence of entire positive and/or non trivial nonnegative solutions. In each case, we provide necessary and sufficient conditions on the exponent $p$ to guarantee the existence of such classical solutions in ${\mathbb R}^n$. This is a joint work with Q.A. Ng\^o, V.H. Nguyen and Q.H. Phan.
