prove that the functional is $alpha$-elliptic

$begingroup$


I got a nonlinear functional who is convex and Gâteaux differentiable. Is there some property of these two that can bring me that the functional is $alpha$-elliptic???

    Can you define $alpha$-convex for us, please?

    Sorry, I mean $alpha$-ellipticity $$biglangle J'left(uright)-J'left(vright),u-vbigranglegeqalpha|u-v|^2_{X},,;forall;u,vin X.$$

    Ah, strongly convex functions. Check the books by Borwein-Vanderwerff and by Zalinescu.

    My functional is coercive, convex and Gateaux differentiable. This can't bring me some strong convexity? without the definition?

    Maybe not. Have you looked at $|x|^p$ for $1<p<+infty$?
