Strongly convexity of a nonlinear functional
$begingroup$
I got the following nonlinear functional
$$Jleft(uright)=frac{1}{2}int_{Omega}left[Hleft(nabla uright)right]^2;dx-int_{Omega}fcdot u;dx,;forall;vin X$$,
where $H$ is a Finsler norm, who is convex.
How to prove that this functional is strongly convex?

This functional is linear on constant functions, so not strongly convex without further assumptions. What is $X$? Is $H$ strongly convex?

$H$ is just a norm who is convex and homogeneous of degree 1, but not linear. I don't know if it is strongly convex. X is just a Hilbert space.
