Streszczenie
It is proved that the multi-dimensional maximal Fejér operator defined in a cone is bounded from the amalgam Hardy space $W(h_{p},\ell_\infty)$ to $W(L_{p},\ell_\infty)$. This implies the almost everywhere convergence of the Fejér means in a cone for all $f\in W(L_{1},\ell_\infty)$, which is larger than $L_1(\mathbb R^d)$.
