A note on Bernstein property of a fourth order complex partial differential equations

Said Asserda

For a smooth strictly plurisubharmonic function $u$ on a open set $Ω \subset C^{n}$ and $F$ a $C^{1}$ nondecreasing function on $R_{+}^{*}$ , we investigate the comp…

Liouville-type results for stationary maps of a class of functional related to pullback metrics

Said Asserda

We study a generalized functional related to the pullback metrics (3). We derive the first variation formula which yield stationary maps. We introduce the stress-energy tensor whic…

Biharmonic Immersion in Cartan Hadamard manifold

Saïd Asserda, M'Hamed Kassi

If $(N^{m + p}, h)$ is a Cartan-Hadamard manifold such that $R i c (h) \geq - G (r_{N} (x))$ where $G (0) \geq 1, G^{^{'}} \geq 0$ and $G^{- 1/2} \neq \in L^{1} (+ \infty)$ then every proper biharmonic…
