RT Journal Article T1 A generalization of an extensible beam equation with critical growth in RN A1 Cabada Fernández, Alberto A1 Figueiredo, Giovany M. K1 Beam equation K1 Critical exponent K1 Variational methods AB In this work we obtain an existence result for a generalized extensible beam equation with critical growth in $\mathbb{R}^{N}$ of the type $$\Delta^{2}u-M\biggl(\dis\int_{\mathbb{R}^{N}}|\nabla u|^{2} \ dx\ \biggl)\Delta u +u = \lambda f(u)+ |u|^{2^{**}-2}u \ \mbox{in} \ \ \mathbb{R}^{N}, $$ where $N\geq 5$ and $\lambda>0$. The functions $M:[0,+\infty)\rightarrow \mathbb{R}$ and $f:\mathbb{R}\rightarrow \mathbb{R}$ are continuous. Since there is a competition between the function $M$ and the critical exponent given by $2^{**}=\frac{2N}{N-4}$, we need to make a truncation on function $M$. Using the size of $\lambda$, we show that each solution of auxiliary problem is a solution of original problem. Our approach is variational and uses minimax point critical theorems PB Elsevier SN 1468-1218 YR 2014 FD 2014-12 LK https://hdl.handle.net/10347/45927 UL https://hdl.handle.net/10347/45927 LA eng NO Alberto Cabada, Giovany M.
