Complex smooth maps over $(0 , infty) times G$.












1












$begingroup$


Suppose that $G$ is a linear, compact and connected Lie group and that we have a map
$$ u:(0,infty) times G longrightarrow mathbb{C}$$



Also we suppose that for all $t_{0}in(0,infty)$ the map
$u(t_{0},cdot)$ is in $mathcal{C}^{infty}(G,mathbb{C})$ and for all
$x_{0}in G$ the map $u(cdot , x_{0})$ is $C^{infty}((0,infty), mathbb{C})$.



This implies that $u$ is in $mathcal{C}^{infty}((0 , infty) times G$)? If the answer is no, what additional conditions do I need to have
$u$ is in $mathcal{C}^{infty}((0 , infty) times G$)?
