Suppose $F:\mathbb R^n\to \mathbb R$ is a convex continuous function. Moreover, for any $x\in \mathbb R^n$, $$ \limsup_{\lambda\to\infty} \frac {|F(\lambda x)|}{\lambda}<\infty. $$ I would like to conclude that the Legendre-Fenchel transform $F^*(y) =\sup_{x\in\mathbb R^n} (<y,x>-F(x))$ is contin...
