Streszczenie
We establish a Banach–Steinhaus type theorem for nonlinear functionals of several variables. As an application, we obtain extensions of the recent results of Balcerzak and Wachowicz on some meager subsets of $L^1(\mu )\times L^1(\mu )$ and $c_0\times c_0$. As another consequence, we get a Banach–Mazurkiewicz type theorem on some residual subset of $C[0,1]$ involving Kharazishvili's notion of ${\mit\Phi} $-derivative.
